本文从便于实施的角度提出将一种交织－ＲＳ码纠错技术用于自适应流星突发（Ｍｅｔｅｏｒ－Ｂｕｒｓｔ）通信。为得到较佳的自适应纠错策略，将用最优化方法搜索出在给定条件下使分组成功译码概率达到最大时的最佳交织深度和最佳码长。从几种不同差错控制方案的比较来看，采用分段编码和交织技术能有效地改善ＭＢ通信系统的性能。

In this paper an error correction technique of interleaving RS code is suggested being used in adaptive meteor burst communications for the purpose of implementation simplicity.In order to get good strategies of error correction,optimization method is employed to find optimum interleaving depth and optimum code length under given condition such that the successful decoding probability of a block is maximum.Comparison of several different schemes of error control shows that the performance of MB communication systems can be effectively improved by using the technique of segmental coding and interleaving.In addition,analysis is made based on numerical results and some useful conclusions are derived.
