Simulation and Analysis of Iterative Encoding and Decoding of Serially Concatenated Convolutional Codes

串行级联卷积码SCCC(SeriallyConcatenatedConvolutionalCodes)是近年来提出的一种性能较好的信道编码方式,它由两个串行的反馈系统卷积码RSC(RecursiveSystematicConvolutionalcodes)和一个内交织器构成。通过计算机仿真,分析了在进行SCCC码设计时,参数的选择对于SCCC码纠错性能的影响,提出了设计SCCC码时选择参数的方法。

Serial Concatenated Convolutional Codes(SCCC) is a better scheme presented recently for channel coding.This scheme employ two Recursive Systematical Convolutional Codes(RSC) and an inner interleaver.In the paper we undertake a comprehensive study of the characteristics of SCCC' bit error rate performance,which enables us to choose proper design parameters in accordance to specific requirements by computer simulation.
