摘　　要：在数据链系统中,RS译码可以采用纠错译码,也可以采用纠错纠删译码。CCSK作为数据链系统的关键技术之一,解调依据是最大互相关值,CCSK的阈值设定对系统性能有较大影响。研究了CCSK阈值的选取对纠错纠删RS译码数据链系统性能的影响,采用Matlab仿真工具,设定不同的CCSK阈值,找到使系统性能达到最好的CCSK阈值,并与只进行纠错的RS译码系统进行对比。仿真结果表明,在高斯白噪声下,当CCSK阈值取14时,纠错纠删RS译码要比只进行纠错的RS译码性能改善很多。In data link system,the RS decoding can adopt error correction decoding,and also error?and?erasure correcting decoding. The CCSK is one of the main techniques of data link system,whose demodulation is based on the maximum cross?cor?relation value. The CCSK threshold set has great impact on system performance. The influence of CCSK threshold selection on the performance of the data link system with RS error?and?erasure correcting decoding is studied in this paper. The Matlab simu?lation tool is used to set the different CCSK thresholds,find out the CCSK threshold to reach the best system performance,and compare with the RS decoding system with error correction only. The simulation results show that,under Gaussian white noise, the performance of error?and?erasure correcting RS decoding is better than that of the RS decoding with error correction only when CCSK threshold is 14.
