A Comprehensive Review of Low Density Parity Check Encoder Techniques

This paper presents a survey on various technologies of low density parity check encoder. LDPC codes are capable to handle high speed communication channel, by reducing attenuation, hazards and efficiently rectifying the linear error correction. Various coding technologies used in new generation communication system, such as turbo code, hamming code, low-density parity check (LDPC) code and Bose–Chaudhuri–Hocquenghem (BHC) code, are widely used in recent communication system. The LDPC has technical remarkable advantages and better performance in high speed communication process compared to turbo code. This paper deals with study of LDPC encoding techniques with various methods of detecting error and its correction. Here classification and performance analysis of LDPC encoding techniques on the basis of resources utilization, systematic, non-systematic approaches and consumer data right etc. have been analyzed in this paper. Apart from above mentioned criteria, this study deals with hardware and software architecture of LDPC encoder in rectification of forward error correction, parallel execution of instruction set. This study and analysis could offer scalability, the future scope of improving the performance of LDPC encoder in all aspects of the next generation communication process. This paper gives overview of various LDPC encoder applications, drawbacks and solution to overcome it.
