A channel coder design for a novel high speed communication system

A technique used for controlling the errors in data transmission over a noisy channel is known as Channel coding. Low Density Parity Check(LDPC) codes and also Turbo codes approaches Shannon capacity limit. In this paper, the performance of Quasi Cyclic(QC) LDPC codes and Random LDPC codes are compared in terms of error. The code which is appropriate for hardware implementation in terms of structural complexity is identified here. The BER performances of QC-LDPC and Turbo codes are analysed. The channel coder which is more suitable for a high speed communication system is identified in this paper.
