Sparse code multiple access (SCMA), which combines the advantages of low density signature (LDS) and code-division multiple access (CDMA), is regarded as one of the promising modulation technique candidate for the next generation of wireless systems. Conventionally, the message passing algorithm (MPA) is used for data detector at the receiver side. However, the MPA-SCMA cannot be implemented in the next generation wireless systems, because of its unacceptable complexity cost. Specifically, the complexity of MPA-SCMA grows exponentially with the number of antennas. Considering the use of high dimensional systems in the next generation of wireless systems, such as massive multi-user MIMO systems, the conventional MPA-SCMA is prohibitive. In this paper, we propose a low complexity detector algorithm named the expectation propagation algorithm (EPA) for SCMA. Mainly, the EPA-SCMA solves the complexity problem of MPA-SCMA and enables the implementation of SCMA in massive MU-MIMO systems. For instance, the EPA-SCMA also enables the implemantation of SCMA in the next generation wireless systems. We further show that the EPA can achieve the optimal detection performance as the numbers of transmit and receive antennas grow. We also demonstrate that a rotation design in SCMA codebook is unnecessary, which is quite rather different from the general assumption.

This research addresses the problem inter-symbol interference (ISI) using equalization techniques for time dispersive channels with additive white Gaussian noise (AWGN). The channel equalizer is modelled as a non-linear Multilayer Perceptron (MLP) structure. The Back Propagation (BP) algorithm is used to optimize the synaptic weights of the equalizer during the training mode. In the typical BP algorithm, the error signal is propagated from the output layer to the input layer while the learning rate parameter is held constant. In this study, the BP algorithm is modified so as to allow for the learning rate to be variable at each iteration and this achieves a faster convergence. The proposed algorithm is used to train the MLP based decision feedback equalizer (DFE) for time dispersive ISI channels. The equalizer is tested for a random input sequence of BPSK signals and its performance analysed in terms of the Bit Error Rates and speed of convergence. Simulation results show that the proposed algorithm improves the Bit Error Rate (BER) and rate of convergence.

An efficient Viterbi decoder is introduced in this paper; it is called Viterbi decoder with window system. The simulation results, over Gaussian channels, are performed from rate 1/2, 1/3 and 2/3 joined to TCM encoder with memory in order of 2, 3. These results show that the proposed scheme outperforms the classical Viterbi by a gain of 1 dB. On the other hand, we propose a function called RSCPOLY2TRELLIS, for recursive systematic convolutional (RSC) encoder which creates the trellis structure of a recursive systematic convolutional encoder from the matrix “H”. Moreover, we present a comparison between the decoding algorithms of the TCM encoder like Viterbi soft and hard, and the variants of the MAP decoder known as BCJR or forward-backward algorithm which is very performant in decoding TCM, but depends on the size of the code, the memory, and the CPU requirements of the application.

Authors: Jayaraman.G1, VeeraKumar K2, Selvakani.S3 Abstract— In communication system, it is aimed to provide highest possible transmission rate at the lowest possible power and with the least possible noise. MIMOOFDM has been chosen for high data rate communications and widely deployed in many wireless communication standards. The major drawback in OFDM signal transmission is high PAPR. In previous, use clipping technique to tackle this problem. In this paper, use EM-GAMP algorithm to reduce PAPR in considerable amount.

Empirical mode decomposition (EMD) is an effective noise reduction method to enhance the noisy chaotic signal over additive noise. In this paper, the intrinsic mode functions (IMFs) generated by EMD are thresholded using multivariate denoising. Multivariate denoising is multivariable denosing algorithm that is combined wavelet transform and principal component analysis to denoise multivariate signals in adaptive way. The proposed method is compared at a various signal to noise ratios (SNRs) with different techniques and different types of noise. Also, scale dependent Lyapunov exponent (SDLE) is used to test the behavior of the denoised chaotic signal comparing with clean signal. The results show that EMD-MD method has the best root mean square error (RMSE) and signal to noise ratio gain (SNRG) comparing with the conventional methods.

We discussed most of what one wishes to learn in vector calculus at the undergraduate engineering level. Its also useful for the Physics ‘honors’ and ‘pass’ students. This was a course I delivered to engineering first years, around 9th November 2009. But I have added contents to make it more understandable, eg I added all the diagrams and many explanations only now; 14-18th Aug 2015. More such lectures will follow soon. Eg electromagnetism and electromagnetic waves !

In digital communication forward error correction methods have a great practical importance when channel is noisy. Convolutional error correction code can correct both type of errors random and burst. Convolution encoding has been used in digital communication systems including deep space communication and wireless communication. The error correction capability of convolutional code depends on code rate and constraint length. The low code rate and high constraint length has more error correction capabilities but that also introduce large overhead. This paper introduces convolutional encoders for various constraint lengths. By increasing the constraint length the error correction capability can be increased. The performance and error correction also depends on the selection of generator polynomial. This paper also introduces a good generator polynomial which has high performance and error correction capabilities.

Viterbi decoder is the most important part in receiver section of wireless communication system. Viterbi algorithm is one of the most common decoding algorithms used for decoding convolutional codes. Viterbi decoder employs Maximum Likelihood technique to decode the convolutionally encoded data stream. In practice, most of the communication systems use Viterbi decoding scheme in processors. But increased interest on high speed Viterbi decoder in a single chip forced to realize with the speed of Giga-bit per second, without using memory or off-chip processors. Implementation of proposed design and realization is possible due to advanced Field Programmable Gate Array (FPGA) technologies and advanced Electronic Design Automatic (EDA) tools. This paper involves designing an optimum structure of Viterbi decoder and implementing it on different FPGA devices to compare the resource utilizations.

Equalization techniques have long been used to counteract effects of communication channels and non-linearities. Traditional nonlinear equalization techniques however are fraught with challenges. As such, research has been ongoing for defining the equalization problem as a classification problem. With this, machine learning techniques can be applied. In lieu of that approach, support vector machine techniques provide an efficient way to define boundaries for classifying non-linear symbol constellations in communication systems. Using BPSK modulation as a baseline with a two-tap channel filter model, this research goes on to validate the application of support vector machine techniques to correctly define symbol boundaries. The performance of support vector machines is directly related to the SNR and extent of non-linearities. However, the bit-error-rate performance shows that this approach is viable, providing results comparable to traditional methods as well as neural networks. As a further addition to the results in the reference paper, this research shows that SVM’s don’t generalize to different channel conditions as well as different SNRs to the ones that are defined for the training dataset. A filter bank SVM approach shows that it can be used to improve BER performance in these varying conditions.

This paper describes a novel audio coding algorithm that is a building block in the recently standardized 3GPP EVS codec. The presented scheme operates in the Modified Discrete Cosine Transform (MDCT) domain and deploys a Split-PVQ pulse coding quantizer, a noise-fill, and a gain control optimized for the quantizer’s properties. A complexity analysis in terms of WMOPS is presented to illustrate that the proposed Split-PVQ concept and dynamic range optimized MPVQ-indexing are suitable for real-time audio coding.
