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.

A novel Code-Matched interleaver is proposed which decreases the number of the low weight codewords to improve the performance of the Turbo code. The modified design can adapt more kinds of Turbo codes determined by the generator matrix, while it doesn't decrease the bit error rate performance of Turbo codes at moderate to high signal to noise ratio. At the same time, in Rayleigh fading channel, the new Code-Matched interleaver can also debase the error floor.
