接近香农限的编织卷积码设计与仿真
0
()
摘要:
本文主要阐述了斜纹编织卷积码的编码结构、迭代译码以及活性距离和交织器对其误码性能的影响等基本概念。通过系统仿真,在AWGN信道下发现斜纹编织卷积码的系统性能与系统传输帧长和编码器个数都有很大的联系,其误码性能十分接近香农限,且没有错误地板效应。

Design and Simulation of WCCs near to Shannon Limit
()
Abstract:
This paper mainly illustrates the effect of encoder structure,iterative decoding and active distance and interleaver of Woven Convolutional Codes(WCCs) with twill structure on its error-correcting performance.Simulation results of WCCs with twill structure over AWGN show that the BER performance is affected greatly by the transmission frame length and the number of encoders,which also indicate that the error-correcting performance approaches Shannon limit and has no error floor.
Key words:  Woven convolutional code(WCC),Iterative decoding,Active distance,Interleaver,Design
