Abstract—In this paper, the performance analysis of OFDM based system using turbo and LDPC coding technique is presented under Nakagami-m fading channel. Nakagami-m is very recent and useful tool to evaluate the channel performance for OFDM system. The optimum value of parameter m = 1.4 is used in this paper. Here comparative analysis of turbo coding and LDPC coding schemes shows that error performance of LDPC is much better as compared to turbo codes. Both coding scheme revels the enhancement in BER performance in Nakagami-m channel.
Index Terms—COFDM, nakagami-m fading, turbo codes, low density parity codes.
