摘要

本文分析了选择性重复(SR)协议在衰落无线信道中的吞吐量。隐马尔可夫模型(HMM)可以很好地逼近衰落的无线信道，但对于以隐马尔可夫模型为特征的信道，无法计算SR吞吐量。我们使用矩阵权重的梅森流图的泛化来进行分析，从而得到传输石灰的力矩生成函数，从而计算吞吐量。我们的方法是通用的，可以应用于任何有限状态马尔可夫通道。它也可以用来分析SR协议的延迟

Throughput Analysis of Selective Repeat ARQ in Fading Wireless Channels

This work analyzes the throughput of selective repeat (SR) protocol in fading wireless channels. Hidden Markov models (HMM) provide a good approximation to the fading wireless channel, hut the calculation of SR throughput has been unavailable for channels characterized by HMM. We use a generalization of Mason's flow graphs with matrix weights for our analysis, leading to the moment generating function of the transmission lime, and thus calculating the throughput. Our methodology is general and can be applied for any finite-state Markov channels. It can also be used to analyze the delay of SR protocol
