Description
Summary:This work considers the bit error rate (BER) performance of turbo product codes (TPC) constituted from low density parity check (LDPC) codes with non-sequential decoding (NSD). The BER of the TPC-LDPC is evaluated for LDPC codes with various rates and sizes using the bit flipping (BF) and sum product (SP) algorithms. Monte Carlo simulation results demonstrate that NSD can provide a remarkable additional coding gain of about 3.5 dB using the BF algorithm as compared to sequential decoding. Moreover, simulation results confirmed that the order of the turbo and LDPC decoding iterations can have a noticeable impact on the BER. Similarly, the NSD of TPC-LDPC codes using the SP algorithm offered noticeable improvement for particular codes.
