摘要 介绍了规则LDPC码的构造方式和译码算法;在二元AWGN(加性白高斯噪声)环境下,对不同的参数条件,从传输误码性能和译码复杂度两方面,将规则LDPC码与Turbo码进行了对比.仿真结果表明规则LDPC码在中短帧传输下具有良好的性能,这对LDPC码投入实际应用具有重要的意义. The principles of encoding and decoding schemes to regular low - density parity check(LDPC) codes are given in the paper. The BER and decoding complexity performances to regular LDPC codes compared with Turbo code are simulated over AWGN channel given specific code parameters. The results show that regular LDPC codes have good performances over turbo codes for the short and middle transmitting frames.
