摘　　要：本文针对无线信道接入协议在教学过程中存在理论分析抽象和学生理解困难的实际问题,设计了一种基于Matlab的无线信道接入协议仿真平台,可灵活地刻画物理层信号样式和信道传输模型。通过建立衰落信道接下接入协议的吞吐量和时延数学模型,以典型的Nakagami信道模型为例,仿真分析了捕获效应对接入协议吞吐量的影响。仿真平台有助于学生掌握无线信道接入协议知识要点,在教学实践中获得了很好的效果。A teaching experiment simulation platform based on Matlab is designed in this paper,evaluation and characterization of wireless channel access protocol can be easily conducted by abundant channel models and media access protocols in this platform. As an example,the evaluation of capture effect under Nakagami wireless channel to throughout delay is investigated,detail numerical simulation results are discussed. The elementary teaching prac-tices show that the experiment simulation platform is helpful for students to understand and master the key knowl-edge points in wireless MAC protocols.
