This paper work focuses on performance analysis of PAPR reduction of orthogonal frequency division multiplexing (OFDM) using amplitude clipping & filtering based design. Now a days one of the most proficient multi-carrier transmission techniques widely used today is orthogonal frequency division multiplexing (OFDM) which has been implemented by the next generation wireless communication technology: Long Term Evolution (LTE). Extra robustness to multipath fading and impulse noise is provided OFDM. It eliminates inter symbol interference (ISI) & inter carrier interference (ICI) with certain procedure. Therefore peak to average power ratio (PAPR) is the basic problem with OFDM. However in this paper we proposed a reduction procedure of the PAPR by using clipping and filtering. Here we use a composed high pass , low pass & Chevyshev band pass filter II after amplitude clipping to reduce the PAPR. The performance of the system in terms of bit error rate (BER) and symbol error rate (SER) is also investigated as a new filter based clipping method is proposed. Our proposed clipping method with and composed high pass the Chevyshev bandpass filter II in PAPR performance of the system with a little compromise of BER & SER showing the significant improvement in Quadrature Amplitude Modulation (QAM).

This paper investigates transparent wavelength routed optical networks using three different fiber types NZDSF, SMF and PSCF - and validates the effectiveness of Hybrid Raman/EDFA Fiber Amplification (HFA) with different pumping levels, up to the moderate 60% pumping regime. Nodes operate on the basis of flexible-grid elastic NyWDM transponders able to adapt the modulation format to the quality-of-transmission of the available lightpath, exploiting up to five 12.5 GHz spectral slots. Results consider a 37node Pan-European network for variable Raman pumping level, span length and average traffic per node. We show that HFA in moderate pumping regime reduces the power consumption and enhances spectral efficiency for all three fiber types with particular evidence in NZDSF. In essence to that, introduction of HFA is also beneficial to avoid blocking for higher traffic loads.

Wireless communication system with multi- antenna arrays has been a field of intensive analysis on the last years. The appliance of multiple sending antennas and Receiving Antennas either side will considerably enhance the data rate and rate. The review of the performance limitations of MIMO system becomes vital since it will provide lot ideas in understanding and planning the important life MIMO systems. Vertical Bell Laboratories layered space Time (V-BLAST). The thought behind Multiple Input and Multiple Output system is that the signals on the transmitter antennas at one finish and also the receiver antennas at the opposite finish are correlative in such how that the performance (Bit Error Rate or BER) or the info rate (bits/sec) of the wireless communication system for every MIMO subscriber are improved. During this paper we tend to are proposing a technique that evaluates the performance of V-BLAST MIMO system in several thought of Rayleigh attenuation surroundings to urge higher performance of the system. In V- BLAST MIMO system a number of linear detection techniques will be used for interference cancellation. At this point we are using MMSE-IC for the same. Our expected system provide higher error rate performance with the used of matched filter at receiver aspect .The projected system compared within the presence of AWGN. Now matched filter applied on V- BLAST MIMO with MMSE-IC system in fading diversity surroundings.

Recent developments in broadband wireless technology heightened the need for WiMAX which assures high-speed data services. Mobile WiMAX is grounded on orthogonal frequency division multiplexing/orthogonal frequency division multiplexing Access (OFDM/OFDMA) technology which is an increasing important technique in LTE systems. This paper describes the OFDM transceiver implementation using software-defined radio system (SDR). A SDR is a radio communication system where elements have been generally implemented in hardware are rather implemented by software on a personal computer. In this paper, the software part is realized using GNU Radio and the hardware part is implemented using USRP N210. OFDM poses a problem of a Peak to Average Power Ratio (PAPR) or high crest factor. To stave off this problem either High Power Amplifiers (HPAs) with large dynamic range or PAPR reduction techniques are used. The former scheme raises cost of the system, while the latter induces redundancy or distortion. This paper presents a novel architecture (which combines channel coding and clipping) for the PAPR reduction and analyzes various parameters which effects the performance of OFDM such as power spectral density, the crest factor and BER. Channel coding part is framed of three steps randomization, Forward Error Correction (FEC) and interleaving. In clipping, certain threshold limits the amplitude of time domain samples. Without filtering, clipping causes out-of-band radiation. The paper analyzes the out band radiation value (at 2.395 GHz) and PAPR reduction with respect to clipping threshold value. This scheme is preferred because of its lower complexity and hence would be cheaper to implement than conventional reduction techniques. Experimental results prove that the clipping method reduced PAPR significantly as the number of clip and filtering level is increased.

Orthogonal frequency division multiplexing (OFDM) is a multicarrier modulation (MCM) technique that divides the wide bandwidth into parallel narrow bands, each of which is modulated by orthogonal subcarriers. Currently, OFDM is a high-spectral efficiency modulation technique that is used in a variety of wired and wireless applications. The transmitted signal in a wireless communication channel spreads from transmitter to receiver through multiple reflective paths. This triggers multipath fading, which causes variations in the received signal's amplitude and phase. Slow/fast and frequency-selective/frequency-nonselective are the main types of multipath fading channels. Therefore, in this paper, we proposed new models for modeling multipath fading channels, such as the exponential fading channel and the Gamma fading channel. In addition, new bit-error-rate (BER) derivations have been derived. The performance of the OFDM system over proposed channel models has been evaluated using Monte-Carlo simulation and compared to the Rayleigh fading channel model. The obtained results via simulations show that the exponential fading channel at a rate parameter (λ=0.5) outperforms the Rayleigh fading channel by 6 dB for all values of Eb/No, while the Gamma fading channel at (α=2) outperforms the Rayleigh fading channel by 3 dB for all values of Eb/No.

A new work has been proposed in this paper in order to overcome one of the main drawbacks that found in the Orthogonal Frequency Division Multiplex (OFDM) systems, namely Peak to Average Power Ratio (PAPR). Furthermore, this work will be compared with a previously published work that uses the neural network (NN) as a solution to remedy this deficiency. The proposed work could be considered as a special averaging technique (SAT), which consists of wavelet transformation in its first stage, a globally statistical adaptive detecting algorithm as a second stage; and in the third stage it replaces the affected peaks by making use of moving average filter process. In the NN work, the learning process makes use of a previously published work that is based on three linear coding techniques. In order to check the proposed work validity, a MATLAB simulation has been run and has two main variables to compare with; namely BER and CCDF curves. This is true under the same bandwidth occupancy and channel characteristics. Two types of tested data have been used; randomly generated data and a practical data that have been extracted from a funded project entitled by ECEM. From the achieved simulation results, the work that is based on SAT shows promising results in reducing the PAPR effect reached up to 80% over the work in the literature and our previously published work. This means that this work gives an extra reduction up to 15% of our previously published work. However, this achievement will be under the cost of complexity. This penalty could be optimized by imposing the NN to the SAT work in order to enhance the wireless systems performance. Orthogonal Frequency Division Multiplexing

Spread-spectrum communication, with its inherent interference attenuation capability, has over the years become an increasingly popular technique for use in many different systems. They have very beneficial and tempting features, like Antijam, Security, and Multiple accesses. This thesis basically deals with the pseudo codes used in spread spectrum communication system. The cross-correlation and auto-correlation properties of the long Barker Code are analyzed. It has been seen that the length of the code, autocorrelation and cross-correlation properties can help us to determine the best suitable code for any particular communication environment. We have tried to find out the code with suitable auto-correlation properties along with low cross-correlation values.

This paper presents a hardware architecture of complex K-best Multiple Input Multiple Output (MIMO) decoder reducing the complexity of Maximum Likelihood (ML) detector. We develop a novel low-power VLSI design of complex K-best decoder for MIMO and 64 QAM modulation scheme. Use of Schnorr-Euchner (SE) enumeration and a new parameter, Rlimit in the design reduce the complexity of calculating K-best nodes to a certain level with increased performance. The total word length of only 16 bits has been adopted for the hardware design limiting the bit error rate (BER) degradation to 0.3 dB with list size, K and Rlimit equal to 4. The proposed VLSI architecture is modeled in Verilog HDL using Xilinx and synthesized using Synopsys Design Vision in 45 nm CMOS technology. According to the synthesize result, it achieves 1090.8 Mbps throughput with power consumption of 782 mW and latency of 0.33 us. The maximum frequency the design proposed is 181.8 MHz.

This paper describes a transformation technique aimed at solving the peak-to-average power ratio (PAPR) problem associated with OFDM (Orthogonal Frequency Division Multiplexing). The Constant Envelop-OFDM solves the problem of high peak-to-average power ratio (PAPR) in OFDM, reducing PAPR to 0 dB. The constant envelope signal can be efficiently amplified with nonlinear power amplifiers thus achieving greater power efficiency. It is shown that CE-OFDMÃ¢â‚¬â„¢s performance is better than conventional OFDM when taking into account the effects of the power amplifier. The performance of CE-OFDM is analyzed in additive white Gaussian noise (AWGN) channel. CE-OFDM is shown to achieve good performance with the use of cyclic prefix transmission. By way of computer simulation, CE-OFDM is shown to compare favorably to conventional OFDM. OFDM and CE-OFDM is analyzed on grounds of BER with additive white Gaussian noise (AWGN). The BER is calculated and the performance of OFDM and CE OFDM is compared.

In this paper, we proposed a particle swarm optimization (PSO) based partial transmit sequence (PTS) technique in order to achieve the lowest Peak-to-Average Power Ratio(PAPR) in Multiple Input Multiple Output- Orthogonal Frequency Division Multiplexing (MIMO-OFDM) systems. Our approach consist of applying the PSO based PTS on each antenna of the system in order to find the optimal phase factors, which is a straightforward method to get the minimum PAPR in such a system. The simulation results demonstrate that the PSO based PTS algorithm when applied to MIMO-OFDM systems with a wide range of phase factors, tends to give a high performance. In addition, there is no need to increase the number of particles of the PSO algorithm to enhance the performance of the system. As a result of this, the complexity of finding the minimum PAPR is kept at a reasonable level.

It is a new concept in town planning, and it may have a highly positive impact on cities and communities. It not only promotes sustainability but also helps increase the health of people and boost the economy. Although it has a lot of advantages, critics argue that this concept is not for all cities and describe its effects as well. New cities should follow this pattern to build and develop their cities

Complex Plane, Modulus, Argument, and Graphical Representation of a Complex Number Hello, my name is Mohammad Ali Nayeem, a student at DIU studying Software Engineering. In Math 102, we delve into various concepts related to complex numbers, including the complex plane, modulus, argument, and their graphical representation. Complex Plane The complex plane is a two-dimensional plane used to visually represent complex numbers. It consists of a horizontal axis (the real axis) and a vertical axis (the imaginary axis). Any complex number 𝑧 = 𝑎 + 𝑏 𝑖 z=a+bi can be plotted on this plane, where 𝑎 a is the real part and 𝑏 b is the imaginary part. Modulus The modulus (or absolute value) of a complex number 𝑧 = 𝑎 + 𝑏 𝑖 z=a+bi is the distance of the point representing 𝑧 z from the origin (0, 0) in the complex plane. It is denoted by ∣ 𝑧 ∣ ∣z∣ and calculated using the formula: ∣ 𝑧 ∣ = 𝑎 2 + 𝑏 2 ∣z∣= a 2 +b 2 The modulus provides a measure of the magnitude of the complex number. Argument The argument of a complex number is the angle 𝜃 θ between the positive real axis and the line segment connecting the origin to the point representing the complex number. It is denoted by arg ⁡ ( 𝑧 ) arg(z) and is usually measured in radians. The argument can be found using the formula: 𝜃 = tan ⁡ − 1 ( 𝑏 𝑎 ) θ=tan −1 ( a b ) The argument indicates the direction of the complex number in the complex plane. Graphical Representation To graphically represent a complex number 𝑧 = 𝑎 + 𝑏 𝑖 z=a+bi, plot the point ( 𝑎 , 𝑏 ) (a,b) on the complex plane. The modulus is the length of the line from the origin to this point, and the argument is the angle this line makes with the positive real axis. For example, the complex number 3 + 4 𝑖 3+4i can be plotted as the point (3, 4). Its modulus is: ∣ 3 + 4 𝑖 ∣ = 3 2 + 4 2 = 5 ∣3+4i∣= 3 2 +4 2 =5 Its argument is: 𝜃 = tan ⁡ − 1 ( 4 3 ) ≈ 0.93 radians θ=tan −1 ( 3 4 )≈0.93 radians Understanding these concepts helps in visualizing and manipulating complex numbers, which are fundamental in many areas of engineering and applied mathematics.

Our CPM guide includes everything you need to get started in the Critical Path Method - with step-by-step examples, solutions, as well as schedules to help get your next project done faster and easier. The Critical Path Method (CPM) is a simple but powerful technique for analyzing, planning, and scheduling large, complex projects. It is used to determine a project’s critical path—the longest sequence of tasks that must be finished for the entire project to be complete. CPM, also known as Critical Path Analysis (CPA), identifies dependencies between tasks, and shows which tasks are critical to a project. The Critical Path Method (CPM) is one of the most important concepts in project management, and certainly among the most enduring. But what is the Critical Path Method, exactly? This beginner-friendly guide will help you understand the Critical Path Method and apply it in your projects. Early iterations of the Critical Path Method can be traced all the way back to the Manhattan Project in the early 1940s. Given the ambition, scale, and importance of this world-altering project, scientists - and the managers behind them - developed a number of techniques to make sure that the project delivered results on time. For a project management technique, the Critical Path Method has quite an illustrious history. One of these techniques was to map out the most important tasks in any project and use that to estimate the project completion date. The Critical Path Method in project management is a cornerstone of project planning even to this day. How long a project takes often depends on the most important tasks that constitute it.
