In this paper, we evaluate packet error rate (PER) performances of high data rate multiband OFDM systems over 1 Gbps in CM 3 using irregular structured LDPC code, simplified LDPC code, and array LDPC code.We also evaluate the decoding complexities of simplified LDPC code and array LDPC code with code rates of R = 3/4, 7/8, when belief propagation (BP) algorithm is used. From simulation results, we show that at data transmission rates of 640, 960 Mbps, simplified LDPC codes have the best error rate performances, and at data transmission rate of 1120 Mbps, array LDPC code has better error rate performances than simplified LDPC code. We also show that the order of decoding complexity for array LDPC code and simplified LDPC codes are same.
