编织卷积码(WovenConvolutionalCodes)是近年来所出现的一种新型高效纠错码,其中交织器的设计对分散突发错误、改善其纠错性能起着决定性的作用。传统的编织卷积码采用了行进列出的简单的交织方式,本文针对编织卷积码的结构特性设计了两种不同的交织器并通过系统仿真比较了它们的性能,仿真结果显示行式交织器极大地改善了系统性能,是目前为止最优的编织卷积码的交织器。
WovenConvolutionalCodes is a new type of high efficiency error correction code that appears in recent years. The design of interleaver plays a decisive role in distributing burst errors and improving error correction performance. The traditional weaving convolutional code adopts the simple interleaving way listed in the paper. In this paper, we design two different interleavers for the structural characteristics of braided convolutional codes and compare their performances through system simulation. The simulation results show that the interleaved lines The system greatly improves system performance and is by far the best interleaver for weaving convolutional codes.
