This document provides an overview of high speed board design for signal integrity. It discusses transmission line parameters including capacitance, inductance, resistance, and shunt conductance. It describes how signal propagation causes electric and magnetic fields based on dV/dt and dI/dt. Key signal integrity issues are covered such as impedance mismatching causing reflections, crosstalk from electromagnetic coupling, and rail collapse in power distribution systems. Methods to minimize these issues include controlling transmission line characteristics, maintaining consistent impedance, and using Faraday cages to isolate noise.
The document summarizes a seminar presentation on Red Tacton, a human area network technology developed by a Japanese company. Red Tacton allows data transmission over the surface of the body at speeds of up to 10Mbps using weak electric fields. It consists of transceivers that induce electric fields on the body's surface to transmit data in a way that is safe, using currents much smaller than natural body currents. While innovative, Red Tacton still requires significant research and development to address obstacles like existing popular technologies, costs, and security issues before being widely adopted.

- FMCW radars compete with traditional pulse radars for short-range target detection by providing better visibility near the vessel without gaps close to the bow. However, for longer ranges greater than 100 meters, the performance of FMCW and pulse radars is similar.
- The inherent differences between FMCW and pulse radar technologies include advantages of FMCW for short-range and close-in target detection versus pulse radars, while pulse radars perform better at long ranges and can trigger racon beacons. Both require similar power but FMCW uses thinner cabling.
- SeaHawk is a signal processing technology that improves target detection and resolution for radars by enhancing higher azimuthal frequencies, effectively doubling the antenna size

Security performance analysis for power domain NOMA employing in cognitive ra...journalBEEI
The power domain non-orthogonal multiple access (NOMA) technique introduces one of the fundamental characteristics and it exhibits the possibility of users to decode the messages of the other paired users on the same resources. In cognitive radio inspired NOMA (CR-NOMA), the base station (BS) has to serve untrusted users or users with different security clearance. This phenomenon raises a security threat particularly in such CR-NOMA. This paper develops a tractable analysis framework to evaluate the security performance of cooperative non-orthogonal multiple access (NOMA) in cognitive networks, where relay is able to serve two far NOMA users in the presence of external eavesdropper. In particular, we study the secrecy outage probability in a two-user NOMA system. This situation happens in practical the BS is pairing a legitimate user with another untrusted user. Main reason is that the non-uniform distribution in terms of trusted and untrusted users in the cell. By performing numerical results demonstrate the performance improvements of the proposed NOMA scheme in comparison to that of several situations in terms of different parameters. Furthermore, the security performance of NOMA is shown to verify the derived expressions.

Power-Grid Load Balancing by Using Smart Home AppliancesValerio Aisa
Climate change is one of the greatest environmental, social and economic threats facing the planet, and can be mitigated by increasing the efficiency of the electric power generation and distribution system. Dynamic demand control is a low-cost technology that fosters better load balancing of the electricity grid, and thus enable savings on CO2 emissions at power plants. This paper discusses a practical and inexpensive solution for the implementation of dynamic demand control, based on a dedicated peripheral for a general-purpose microcontroller. Pre-production test of the peripheral has been carried out by emulating the actual microprocessor. Simulations have been carried out, to investigate actual efficacy of the proposed approach.
1. The Trans-Pacific Grid Datafarm testbed provides 70 terabytes of disk capacity and 13 gigabytes per second of disk I/O performance across clusters in Japan, the US, and Thailand.
2. Using the GNET-1 network testbed device, the Trans-Pacific Grid Datafarm achieved stable transfer rates of up to 3.79 gigabits per second during a file replication experiment between Japan and the US, near the theoretical maximum of 3.9 gigabits per second.
3. Precise pacing of network traffic flows using inter-frame gap controls on the GNET-1 device allowed for high-speed, lossless utilization of long-haul trans-Pacific network links.

This document summarizes the performance measurements taken on a 40-channel 10G DWDM system operated by Bharath Sanchar Nigam Limited in India. The key findings were:
1. Optical power levels were measured for each channel at different points in the system. Some channels showed power levels indicating a fault in the respective fiber cable.
2. Parameters like noise figure, gain, polarization mode dispersion and dispersion were analyzed to identify limitations and suggest improvements to optimize the system.
3. Nonlinear impairments like four-wave mixing, self-phase modulation and stimulated Raman/Brillouin scattering were also evaluated to determine their impact based on number of channels, channel power, and fiber properties
On the Performance Analysis of Multi-antenna Relaying System over Rayleigh Fa...IDES Editor
In this work, the end-to-end performance of an
amplify-and-forward multi-antenna infrastructure-based relay
(fixed relay) system over flat Rayleigh fading channel is
investigated. New closed form expressions for the statistics of
the received signal-to-noise ratio (SNR) are presented and
applied for studying the outage probability and the average
bit error rate of the digital receivers. The results reveal that
the system performance improves significantly (roughly 3 dB)
for M=2 over that for M=1 in both low and high signal-tonoise
ratio. However, little additional performance
improvement can be achieved for M>2 relative to M=2 at high
SNR.
This document discusses advancements in photomixing and photoconductive switching devices for terahertz spectroscopy and imaging. It reviews the design methodology and applications of photomixers and photoconductive switches. Photomixers are being used in broadly tunable sweep oscillators and coherent transceivers for high-resolution spectroscopy. Photoconductive switches are used in time-domain spectrometers and illuminators for terahertz impulse radars. Both device types have advantages like broad bandwidth but differ in average power output, with switches producing higher power on average. Careful design of these ultrafast photoconductive devices is important for optimizing their performance and applications.
This document discusses an FPGA implementation of a four phase code design using a modified genetic algorithm. It summarizes the key aspects of the implementation as follows:
1) The proposed architecture efficiently implements a modified genetic algorithm on an FPGA to identify good pulse compression sequences based on discrimination factor.
2) Pulse compression techniques in radar allow long pulses to achieve high energy while maintaining the range resolution of short pulses. The receiver compresses the long signal into a narrow signal.
3) The criteria for good pulse compression sequences include high merit factor and discrimination factor. Merit factor measures quality by comparing main lobe energy to side lobe energy. Discrimination factor compares the main peak to maximum side lobes.
1. WCDMA uses BPSK in the uplink and QPSK in the downlink. Pulse shaping uses RRC (Root-Raised-Cosine) to prevent inter-symbol interference caused by group delay variations during wireless transmission.
2. Pulse shaping is introduced to eliminate noise and facilitate demodulation. WCDMA uses the RRC filter, whose time domain shape is the famous Broadcom logo sinc function.
3. LTE uses SC-FDMA in the uplink and OFDMA in the downlink. OFDM more efficiently uses bandwidth and can accommodate more users. Each OFDM sub-carrier is the Broadcom logo sinc function, with all sub-carriers being orthogonal called
1) Optical fiber detectors include PIN photodiodes, avalanche photodiodes (APDs), and metal-semiconductor-metal (MSM) detectors.
2) PIN photodiodes have high bandwidth but lower sensitivity compared to APDs. APDs have higher sensitivity due to internal gain but lower bandwidth.
3) Key detector characteristics include responsivity, quantum efficiency, bandwidth, dark current, and signal-to-noise ratio (SNR). These characteristics involve tradeoffs and are optimized depending on the application requirements.
