空间站工程PCM体制遥控地址同步字设计及应用

Design and Application of Remote Control Address Synchronization Word with PCM Applied in Spacecraft

在空间站工程中,由于组合体由多个航天器组合而成,需要对各个航天器的遥控地址同步字进行选取设计,以保证各航天器使用的遥控地址同步字除码距满足要求外,在应用过程中还需减小与其他码组组合后触发误结束的概率。通过对启动字与地址同步字组合码字的详细组合分析后,从推荐的42个码样中选取出不建议使用于空间站工程的遥控地址同步字,并对其码字的相关性设计开展详细分析。

In space station project,the combination is assembled by multi-spacecrafts which requires more synchronization words for each crafts respectively to make sure the enough code distance for the lowest probability of error,when combined with other code words.This thesis mainly introduces how to choose the most suitable synchronization word of the 42 synchronization words recommended by ESA,by analysis of the combination of start word and synchronization word in detail.
