摘要
分析了截短RS/混合Ⅱ型ARQ在无线衰落信道上的分组错误率、通过效率、传输时延等特性,给出了数值仿真结果。研究发现,由于RS码具有很强的纠错能力,通过有限次的重传就可达到很低的分组错误率,同时减小了固重传而引起的传输时延。
in this paper, after modelling the mobile channel with a two state Markov chain, theperformances(packet error rate,throughput efficiency and transmission delay )of truncated RS/type II hybridARQ protocol in this fading channel are analyzed and simulated.It is found that,based upon the powerful errorcorrecting capability of RS code,low transmission delay and packet error rate can be obtained by restrictingnumbers of retransmission.
