Performance Analysis of LDPC Convolutional Codes

Low Density Parity Check Convolutional Codes (LDPC-CCs) have the advantage of simple encoding and decoding. ASIC or FPGA implementation of LDPC-CCs have been shown to have very good complexity-performance trade-off. In this paper, we present a class of LDPC-CC and iterative algorithm to decode these codes. The construction technique of our code is simple and easy, compared to other LDPC-CCs, which reduces hardware complexity. The simulation results show that the performance of our proposed codes is better than the LDPC Block codes with the same decoding complexity per information bit. Our code also outperforms its counterpart LDPC-CCs.
