为保证数据传输的可靠性,多种ARQ(自动请求重传)协议被提出和采用。论文针对多种ARQ/混合ARQ协议提出了一个一般化、系统化的时延分析模型,并采用信号流图理论及梅逊公式给出了M步混合ARQ控制系统的时延性能分析结果,为多种ARQ/混合ARQ协议的时延性能分析提供了一种系统化的有效分析方法。
To improve the reliability of transmission, many ARQ protocols have been proposed and adopted In this paper, a generalized and systematic model of the transfer-delay is proposed. An unified expression for the M-Stage HARQ control system is analyzed with the means of SFG (Signal Flow Graphs) and the expressions of Mason. This proposed method offers a systematic and efficient way for obtaining delays of different HARQ protocols.
