摘要 提出一种用于移动数字多媒体的原模图LDPC码,提出的LDPC码的编码算法可以简化编码器的硬件。在AWGN信道仿真结果表明,提出的LDPC码的性能要优于GB20600 LDPC码。 In this paper, a kind of protograph LDPC codes for mobile digital multimedia is proposed, and the encoding algorithms of the proposed LDPC codes can simplify the encoder hardware. The simulation results in AWGN channels show that the BER performance of the proposed codes is much better than that of GB20600 LDPC codes.
