Performance Comparison of LDPC Codes and Turbo Codes

Free registration required

Executive Summary

Low-Density Parity-Check (LDPC) codes can be considered serious competitors to turbo codes in terms of performance and complexity and they are based on a similar philosophy: constrained random code ensembles and iterative decoding algorithms. In this paper, the LDPC codes are coupled with receive diversity techniques and are employed as the error correction scheme over Additive White Gaussian chaNnels (AWGN) by employing Binary Phase Shift Keying (BPSK) modulation scheme. The performance of newly obtained codes is evaluated in term of Bit Error Rate (BER) for a given value of Eb/No.
