摘要

无线分组传输需要一种自适应错误控制编码方案，能够适应不同的码率和非常低的误码率要求，以实现高数据速率传输。串行级联卷积码(SCCC)在中高信噪比范围内比并行级联卷积码(PCCC)具有更低的FER性能，因为SCCC几乎没有错误地板问题。本文提出了一种速率兼容的穿孔SCCC (RCPS)和RCPS- harq系统，以实现自适应和高可靠的错控编码，并介绍了它们在AWGN和多径瑞利衰落信道上的性能。并与速率兼容的穿孔PCCC (RCPP)和W-CDMA系统的一个实例进行了比较。

Rate compatible punctured SCCC

Wireless packet transmission requires an adaptive error control coding scheme that can accommodate varying code rate and very low FER requirements for high data rate transmission. Serial concatenated convolutional codes (SCCC) can provide lower FER performance than parallel concatenated convolutional codes (PCCC) in the region of moderate-to-high SNR because SCCC shows little error-flooring problem. This paper proposes a rate compatible punctured SCCC (RCPS) and RCPS-HARQ system to achieve adaptive and high reliable error control coding, and presents their performance on AWGN and multipath Rayleigh fading channels. Comparative results with rate compatible punctured PCCC (RCPP) and an example of a W-CDMA system are also given.
