摘要
与一般通信链路相比较,宽带数据链中的卫星链路传输距离遥远,因而采用具有高增益的编码技术是数据链卫星链路中必不可少的技术措施.本文阐述了在卫星链路中采用RS码和卷积码的纠错能力,对其级联码的编码增益进行了分析.利用仿真平台对RS码及卷积码纠错性能进行了仿真,并与级联码条件下的仿真结果进行了比较和分析.
Compared with general communication link, the distance of satellite links of wideband data link is so far that high quality coding scheme is essential for data link communication system. This paper discusses the error-correcting abilities of Reed-Solomon coding and convolution coding in satellite links, and analyses the coding gain of these two concatenated codings. The error-correcting abilities of Reed-Solomon coding and Convolution coding were simulated. The simulated results were compared with those of concatenated coding.
