| 摘 要： | 为提高系统可靠传输和吞吐量能力,文中引入一种GBN和SR可切换的混合ARQ技术,该模式利用马尔科夫过程,通过接收端调节ARQ转换状态.仿真结果证实,不管前、后向信道的传输是否经历着马尔科夫错误,系统均表现出较好的性能.

| Abstract: | A hybrid ARQ technology that is convertible between GBN and SR is introduced to satisfy the desired reliablity of tranission and to improve the throughput efficiency.The scheme adjusts ARQ state with reciever by using markov process.Simulation results confirm the corvectness of the analysis and show an improved performance of the system,even when markovian error is occured in the forword and the reverse channels. |
