摘要 分析了在静态多径瑞利衰落信道上应用于正交频分复用技术的非规则LDPC码在相同的调制方式,不同的映射模式下的误码性能,并与规则LDPC码的性能作了比较,结果显示,在静态多径瑞利衰落信道上,不同的映射模式下,非规则LDPC码的误码性能均优于规则LDPC码的误码性能,非规则LDPC码在相同的调制方式下,格雷映射的误码性能优于自然映射的误码性能。 Performance analysis is made using the irregular LDPC codes for the OFDM system based on the static uncorrelated multi- path Rayleigh fading channel and the comparison with regular LDPC codes. It shows that the performance of irregular LDPC codes is better than that of the regular LDPC codes in any modulation and any map code. The BER in Gray map mode is superior to that in nature map mode in performance at the same condition.
