流星突发通信是20世纪中期开始兴起的通信技术。它在可靠性、抗干扰性、生存能力以及费用上的优势使其在民用和军用领域得到广泛研究。主要对流星突发通信中的HARQ技术进行讨论,介绍了固定速率Ⅰ型、变速率Ⅰ型以及Ⅱ型HARQ的工作原理,进行了性能仿真和分析。仿真结果表明采用HARQ方案可以有效改善系统性能,增加吞吐量,Ⅱ型HARQ和变速率Ⅰ型HARQ的性能要优于固定速率Ⅰ型HARQ。
Meteor Burst Communication is the communication technology that began to rise in the middle of the 20th century. Its reliability, immunity, survivability and cost advantages make it widely studied in civil and military applications. This paper mainly discusses the HARQ technology in meteor burst communication, and introduces the working principle of fixed rate type Ⅰ, variable rate type Ⅰ and type Ⅱ HARQ, and performs performance simulation and analysis. The simulation results show that HARQ scheme can effectively improve the system performance and increase the throughput. The performance of type-II HARQ and variable-rate type I HARQ is better than that of fixed-rate type I HARQ.
