提出了一种改进型的Code Matched交织器,它能减少低重量码的数量,从而提高Turbo码的性能。这种改进型的Code Matched交织器可以适用于多种不同生成矩阵产生的Turbo码,而且不会影响Turbo码在中高信噪比处的性能。同时,在Rayleigh信道下,这种交织器能降低错误平台。
An improved Code Matched interleaver is proposed, which can reduce the number of low weight codes and improve the performance of Turbo codes. The improved Code Matched Interleaver can be applied to Turbo codes generated by many different generator matrices without affecting the performance of Turbo codes at high SNR. At the same time, this type of interleaver reduces the false platform under Rayleigh channels.
