摘　　要：为保证遥测系统中的遥测站与中继站之间的无线通信的可靠性,设计基于串行级联编码的无线通信;采用混合纠错的差错控制方式,利用BCH(31,16)纠正三位随机错误、CRC-32检错性能好、交织器能将突发错误变为独立错误的特点,以BCH(31,16)为外码,CRC-32为内码,经交织器变换的串行级联编码;通过研究CRC-32码、BCH(31,16)码、交织器的软件实现方法,实现了遥测系统的数据编、译码及检错、纠错功能;该系统经运行测试,无线通信误码率约为10-5～10-6,稳定可靠,达到了设计要求。In order to assure the reliability of telecommunication between relay station and remote station, telecommunication based on serial concatenation coding has been designed to measure the environmental parameters by remote measurement. The algorithm for coding and decoding and the implementation method of interlace and cancellation interlace by software is researched, Telecommunication data coding and decoding is implemented with the function of error detection and correction. By the designed experimental simulation, the system can run reliably, and the error code rate is about 10^-5～10^-6 which proves the system design accord with the requirements.
