摘　　要：在流星突发通信中,可以采用好的编码技术来提高系统的吞吐量性能。针对流星突发信道的特点,提出了一种基于半速率可逆RS码的混合Ⅱ型ARQ,并对其性能进行了分析,给出了吞吐量的性能公式。从仿真结果可以看出,同已有的基于传统RS码的混合Ⅱ型ARQ相比,这种应用半速率可逆码的混合Ⅱ型ARQ可以使吞吐量性能获得较大的提高。A good code scheme can significantly increase the system throughput for meteor burst communication. According to the features of meteor burst communication, a new type - Ⅱ hybrid ARQ is proposed which is based on half - rate invertible RS code. The throughput performance is analyzed and its expression is derived. Numerical results indicate that compared with classical type -Ⅱ hybrid ARQ this new one can significantly increase the system throughput.
