H.264 video standard is used to achieve high quality video and high data compression when compared to other existing video standards. H.264 uses context-based adaptive variable length coding (CAVLC) to code residual data in Baseline profile.The H.264 bitstream consist of zeros and ones.At one of the decoding stages of contextbased adptive variable length decoder (CAVLD), Total Zeros decoder is ...

This paper considers several linear beamformer design paradigms for multiuser time-invariant multiple-input multiple-output interference channels. Notably, interference alignment and sum-rate based algorithms such as the maximum signal-to-interference-plus noise (max-SINR) algorithm are considered. Optimal linear beamforming under interference alignment consists of two layers; an inner precoder...

Channel coding is commonly incorporated to obtain sufficient reception quality in wireless mobile communications transceiver to counter channel degradation due to intersymbol interference, multipath dispersion, and thermal noise induced by electronic circuit devices. For low energy mobile wireless communications, it is highly desirable to incorporate a decoder which has a very low power consump...

Classical turbo coding base on Parallel Concatenated Convolutional Code has been used for forward error correcting (FEC). From some research reports [1,2,3,5] this technique show new hope to get the coding technique at near Shanon limitation. This paper explains how SOVA decoder works on classical turbo coding. Performance analysis of SOVA decoder is observed by measure the number of bit error ...

A novel pipelined recursive modified Euclidean (ME) algorithm block for the low-complexity, high-speed Reed–Solomon (RS) decoder is presented. The deeply pipelined recursive structure enables implementation of a significantly low-complexity ME algorithm block with much improved clock frequency. The low-complexity, high-speed RS decoder using the pipelined recursive ME algorithm block has been i...

Nonbinary LDPC codes have shown superior performance, but decoding nonbinary codes is complex, incurring a long latency and a much degraded throughput. We propose a low-latency variable processing node by a skimming algorithm, together with a low-latency extended min-sum check processing node by prefetching and relaxing redundancy control. The processing nodes are jointly designed for an optima...

In this paper, we propose a synthesizable LDPC decoder IP core for the WiMAX system with high parallelism and enhanced errorcorrecting performance. By taking the advantages of both layered scheduling and fully-parallel architecture, the decoder can fully support multimode decoding specified in WiMAX with the parallelism much higher than commonly used partial-parallel layered LDPC decoder archit...

In this paper, we address the problem of decoding nonbinary LDPC codes over finite fields GF(q), with reasonnable complexity and good performance. In a first part of the paper, we recall the original Belief Propagation (BP) decoding algorithms and its Fourier domain implementation. We show that the use of tensor notations for the messages is very convenient for the algorihtm description and und...
