摘要

依据卫星星地链路误码率的统计特性,提出一种采用变序列长直接监测链路误码率的新方法.该方法利用误码率分段分析的策略,采用统计学统计置信度原理,并通过对训练序列长度、误差精度和监测可信度进行仿真验证与统计分析,确定了链路监测中序列序列长度的选取准则.实验数据表明,变序列长链路直接监测方法在保证一定信道资源的前提下,有效扩大了链路监测的范围,降低了运算复杂度,在星地链路监测方面具有一定的优越性.%Based on the statistical characteristics of satellite link error rate, this paper proposed a new link directly monitoring technology using variable length sequence. Using the analysis of bit error rate segmentation strategy and statistical principles of statistical confidence, the monitoring method determined the sequence of the link selection criteria through the training sequence length, the error simulation accuracy and reliability of monitoring and statistical analysis. Experimental results show that link directly monitoring technology using variable length sequence is effective to improve the range of link monitoring and reduce the computational complexity under a certain premise of the channel resources. It has certain advantages in the satellite to link monitoring.
