摘要 主要研究了斜纹结构的编织卷积码(WCCs)在编码设计中活性距离和交织器对其性能的影响。通过系统仿真,结果表明在AWGN信道下,发现斜纹WCCs的系统性能将受到系统传输帧长、编码器归零方式及编码器个数的影响,因此适当地选择了编码器和交织器,能使其误码性能更加优越,且没有错误地板效应。 In this paper, the anthors analyze the influence of the active distance and interleaver of WCCs with Twill structure on it's error-correcting performance. Finally, simulation results of WCCs with Twill structure over AWGN show that BER performance is affected greatly by the transmission frame length, return-to-zero mode and the number of encoders, and also indicate that proper selection of encoder and interleaver can improve error-correcting performance greatly and has no error floor.
