1 RB sensitivity at middle RBs poor than other RBs

Pei-Che Chang

1. Measuring LTE sensitivity with a single resource block (RB) located in the middle of the channel can degrade sensitivity. This is because control channels like the primary synchronization signal (PSS), secondary synchronization signal (SSS) and physical broadcast channel (PBCH) are also located in the middle, making decoding more difficult. 2. With a single middle RB, the coding rate needs to be twice as high on subframe 0 compared to other subframes to achieve the same block error rate. This requires at least 3dB higher signal-to-noise ratio (SNR). 3. Testing sensitivity with few RBs near the channel center can also degrade sensitivity slightly due to interference from the in-band

OXX B66 Rx sensitivity and desense analysis issue debug

Pei-Che Chang

This document discusses OXX B66 Rx sensitivity analysis. It calculates the sensitivity for different B66 Rx configurations, including bypassing the external LNA and connecting directly to the mLNA or iLNA. It is determined that connecting to the mLNA yields better sensitivity due to the iLNA's higher noise figure degrading the cascade NF. The document also analyzes desense from Tx leakage into the Rx band and compares to a reference design from another company.

Nonlinearity

Pei-Che Chang

This document contains an agenda and summary of key concepts related to nonlinearity: - Harmonic distortion results in the generation of harmonics that are integer multiples of the fundamental frequency. Higher order harmonics grow with increasing amplitude. - Gain compression occurs when the output amplitude falls below the ideal linear value, reducing receiver sensitivity. - Cross modulation transfers modulation from an interfering signal to the desired signal. - Intermodulation products are generated when two or more signals pass through a nonlinear system, which can fall on the desired channel frequency. - AM/PM conversion undesirably alters the phase of a signal based on its amplitude variations.

Digital modulation techniques updated

Muhammad Mohsin Raza

M-ary Modulation, noise modelling, bandwidth, Bandpass Modulation

DrAimalKhan

This document describes a technique for digitally calibrating the current of a digitally controlled oscillator (DCO) to optimize its phase noise performance across process and temperature variations. The phase error (PHE) signal from a digital PLL is digitized and used to estimate the DCO's phase noise. By adjusting the DCO current digitally based on the estimated phase noise, the optimum operating point with minimum phase noise can be identified. Measurement results on a 90nm CMOS chip demonstrate good correlation between the estimated and measured DCO phase noise, validating the digital calibration approach.

Lecture psk qam, digital modulation

DrAimalKhan

The document discusses phase shift keying (PSK) modulation techniques. It begins by explaining the basic concept of PSK where the phase of a carrier signal is shifted to represent digital data. It then discusses binary PSK (BPSK) where there are two possible phase shifts. It further explains the implementation of M-ary PSK where there are M possible phase shifts, allowing more bits to be transmitted. Finally, it discusses quadrature amplitude modulation (QAM) which combines phase and amplitude modulation to represent data.

Differential stripline impedance calculate

Pei-Che Chang

This document discusses calculating the impedance of differential striplines using three simulation tools and comparing the results. Saturn PCB Toolkit produced an impedance of 77.51 ohms, Polar Si9000 produced 81.32 ohms. Polar was likely more accurate as it uses an EM field solver approach. The document then explores using ADS to calculate impedances of single-ended and differential microstrips, and analyzes a differential line case using the ADS EM model and TDR analysis.

PSK (PHASE SHIFT KEYING )

vijidhivi

The document discusses phase-shift keying (PSK) modulation techniques. It begins with an introduction to PSK and how it uses phases to encode digital data. It then discusses binary phase-shift keying (BPSK) which uses two phases separated by 180 degrees to encode one bit per symbol. BPSK is robust but has a low data rate. Quadrature phase-shift keying (QPSK) is then introduced, which uses four phases separated by 90 degrees to encode two bits per symbol, doubling the data rate of BPSK. Implementations of BPSK and QPSK modulators and demodulators are provided along with diagrams of their constellation plots.

Coherent and Non-coherent detection of ASK, FSK AND QASK

naimish12

This document discusses different digital communication techniques including coherent and non-coherent detection methods for amplitude shift keying (ASK), frequency shift keying (FSK) and quadrature amplitude shift keying (QASK). Coherent detection requires a reference carrier wave and exploits phase information, while non-coherent detection does not require a reference wave. It then describes the receiver designs for coherent and non-coherent detection of ASK and FSK. For QASK, it outlines raising the input signal to the fourth power before bandpass filtering and frequency division to recover the transmitted bit sequence.

Introduction of GPS BPSK-R and BOC

Pei-Che Chang

1) The document discusses the modulation techniques used in various Global Navigation Satellite Systems (GNSS), including GPS, Glonass, BeiDou, and Galileo. 2) GPS uses BPSK-R modulation with a 2.046 MHz bandwidth. Glonass uses FDMA, while the others use CDMA. 3) BOC modulation, used in Galileo, modulates the signal with a subcarrier signal that can be either sine or cosine. This results in a spectral distribution around the subcarrier frequency.

Modulation of digital and analog data

This document discusses various methods of modulating digital and analog data for transmission: 1. It describes digital-to-analog modulation techniques including amplitude shift keying (ASK), frequency shift keying (FSK), phase shift keying (PSK), and quadrature amplitude modulation (QAM). 2. It explains the relationships between bit rate, baud rate, and bandwidth for different modulation schemes. ASK, FSK, and PSK have baud rate equal to bit rate, while higher-order PSK and QAM can have higher bit rates through multiple bits per symbol. 3. Modems and standards like V.32, V.34, and V.90 are discussed in the context of mod

continuos phase frequency shift keying(cpfsk)

Moka Dinesh

This document discusses continuous-phase frequency-shift keying (CPFSK) modulation. CPFSK is a memory-based modulation scheme where the phase is constrained to be continuous, unlike conventional FSK which has abrupt phase shifts. This avoids large spectral side lobes outside the main signal band. CPFSK uses a voltage-controlled oscillator where the phase is determined by integrating the modulated signal. The phase trajectories form a piecewise linear phase trellis. Minimum-shift keying (MSK) is a special case of binary CPFSK with a modulation index of 1/2 and rectangular pulses.

Binary Pass-Band Modulation Techniques

Sugeng Widodo

The document outlines various digital modulation techniques including ASK, BPSK, and FSK. It describes how each technique generates and detects modulated signals. ASK encodes data in signal amplitude levels. BPSK uses two phase shift keying to encode bits. FSK encodes data by shifting the carrier frequency between two values. Optimum detection requires coherent demodulation that correlates the received signal with a reference carrier.

An analysis of pfc converter with high speed dynamic

eSAT Publishing House

This document analyzes the dynamic response of a power factor correction (PFC) converter. It discusses how the bandwidth of the compensator in the output voltage feedback loop affects the transient response. Specifically, it notes that a wider bandwidth improves response but introduces more voltage ripple, while a narrow bandwidth has slower response but less ripple. The document presents modeling of the converter with different levels of voltage ripple and analyzes how it impacts the static behavior and harmonic distortion. Simulation results demonstrate the tradeoff between response, ripple and power quality for low-bandwidth versus high-bandwidth designs.

Phase Locked Loops (PLL) 1

Pei-Che Chang

1) A phase-locked loop (PLL) is a control system that generates an output signal whose phase is related to the phase of an input signal, allowing it to synchronize signals or generate a frequency that is a multiple of the input frequency. 2) In a simple PLL, a phase detector (PD) converts the phase difference between the input and a voltage-controlled oscillator (VCO) output to a voltage, which changes the VCO frequency to follow the input. 3) Ripple in the control voltage to the VCO can produce side bands, so a low-pass filter is used to fix this voltage ripple problem and improve stability.

1) The document presents the Low-Rank Regularized Heterogeneous Tensor Decomposition (LRRHTD) method for subspace clustering. LRRHTD seeks orthogonal projection matrices for all but the last tensor mode, and a low-rank projection matrix imposed with nuclear norm for the last mode, to obtain the lowest rank representation that reveals global sample structure for clustering. 2) LRRHTD models an Mth-order tensor dataset as a (M+1)th-order tensor by concatenating individual samples. It aims to find M orthogonal factor matrices for intrinsic representation and the lowest rank representation using the mapped low-dimensional tensor as a dictionary. 3) LRRHTD formulates an

Brief Introduction About Topological Interference Management (TIM)

Pei-Che Chang

This document discusses topological interference management (TIM) techniques for interference channels. TIM exploits interference alignment principles under realistic channel state information assumptions. The key ideas are: - Focus on canceling strong interference links based on knowledge of the interference pattern - There is a connection between TIM and the index coding problem - The goal of TIM is to maximize degrees of freedom (DoF) based on network topology information - Examples show how transmitting signals over multiple channel uses and exploiting the interference pattern can achieve different DoF values through interference alignment

Patch antenna

Pei-Che Chang

This document discusses patch antennas. It describes the basic structure of a patch antenna, which consists of a radiating metallic patch on a dielectric substrate with a ground plane on the other side. Patch antennas radiate a linearly polarized wave and have a very low profile. Their primary limitation is narrow bandwidth, which is typically less than 5% for single-substrate designs. Common patch antenna geometries include rectangular and circular shapes to generate different beam patterns.

It defines key antenna terminology such as radiation patterns, beamwidth, directivity, gain, polarization, and more. 2. It describes different categories of antenna types including loops, dipoles, slots, reflectors, patches, and more. 3. It covers antenna parameters and concepts such as radiation patterns, beam efficiency, radiation intensity, effective aperture, polarization, near and far field zones, and more.

PAPR Reduction

Pei-Che Chang

This document discusses peak-to-average power ratio (PAPR) reduction techniques for orthogonal frequency-division multiplexing (OFDM) signals. It begins with an introduction to PAPR and its causes for OFDM signals. It then outlines various PAPR reduction techniques including clipping, coding, probabilistic/scrambling, predistortion, and DFT-spreading. Each technique has benefits but also cons such as distortion, reduced efficiency, or increased complexity. The document provides analysis of PAPR characteristics for different OFDM parameters and modulation schemes.

Channel Estimation

Pei-Che Chang

This document discusses various channel estimation techniques for OFDM systems. It describes pilot structures like block, comb and lattice types and how they are suited for different channel conditions. It also explains training symbol based channel estimation techniques like LS and MMSE. DFT-based channel estimation aims to improve performance by eliminating noise outside the channel delay. Decision directed channel estimation updates the channel coefficients without pilots by using detected signal feedback.

Introduction to OFDM

Pei-Che Chang

This document provides an introduction and overview of orthogonal frequency division multiplexing (OFDM). It discusses the limitations of single-carrier transmission at high data rates due to inter-symbol interference (ISI) and the complexity of equalizers. OFDM is presented as a solution that divides the available bandwidth into multiple orthogonal subcarriers. The key concepts of OFDM covered include cyclic prefix, orthogonality of subcarriers, modulation and demodulation, and how the cyclic prefix mitigates ISI between symbols. Bit error rate simulation of an OFDM system is also demonstrated.

The Wireless Channel Propagation

Pei-Che Chang

- The document discusses wireless channel propagation and fading. It covers topics like large-scale fading (path loss and shadowing), small-scale fading (time-selective and frequency-selective fading), and statistical characterization of fading channels. - Small-scale fading is caused by multipath propagation and results in rapid fluctuations in the strength of the received signal over short periods of time or travel distances. It can be time-selective or frequency-selective depending on delay spread and Doppler spread. - Common distributions for modeling fading amplitudes are Rayleigh for non-line-of-sight environments and Rician when there is a dominant line-of-sight path. The document presents models for generating both Rayleigh and Rician fading

Low power architecture of logic gates using adiabatic techniques

nooriasukmaningtyas

The growing significance of portable systems to limit power consumption in ultra-large-scale-integration chips of very high density, has recently led to rapid and inventive progresses in low-power design. The most effective technique is adiabatic logic circuit design in energy-efficient hardware. This paper presents two adiabatic approaches for the design of low power circuits, modified positive feedback adiabatic logic (modified PFAL) and the other is direct current diode based positive feedback adiabatic logic (DC-DB PFAL). Logic gates are the preliminary components in any digital circuit design. By improving the performance of basic gates, one can improvise the whole system performance. In this paper proposed circuit design of the low power architecture of OR/NOR, AND/NAND, and XOR/XNOR gates are presented using the said approaches and their results are analyzed for powerdissipation, delay, power-delay-product and rise time and compared with the other adiabatic techniques along with the conventional complementary metal oxide semiconductor (CMOS) designs reported in the literature. It has been found that the designs with DC-DB PFAL technique outperform with the percentage improvement of 65% for NOR gate and 7% for NAND gate and 34% for XNOR gate over the modified PFAL techniques at 10 MHz respectively.

IJECEIAES

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.
