【摘要】 编织卷积码是近年来出现的一种新型的高效纠错码。该文基于最大斜率(MaximumSlope)卷积码理论,提出了将具有最大斜率的卷积码作为编织卷积码成员码的一种优化设计新方法。系统仿真显示了该种方法在优化编码卷积码的编码器设计方面的显著成效,这对将该方法进一步应用于组合编码领域改善其纠错特性方面有着重要的理论价值。特别是,仿真时我们修改了BCJR译码算法,并增加了行式随机交织器。更多还原

【Abstract】 Woven convolutional codes(WCCs)introduced in recent years is a new efficient error-corrective codes.In this paper,we present a novel optimizing design method that the convolutional codes with maximum slope are used as the component codes of woven convolutional codes.The system simulation results show that the error-correcting performance of WCCs is improved greatly.It is of greatly theoretical values for the method to be applied in the field of combination codes to improve performance of error controlling.Particularly,we modified BCJR decoding algorithm and added row-wise random interleaver.更多还原
