优先级与自适应PRMA协议的性能研究

Performance Research on PRMA with Priority and Adaptability

本文对未来的第三代微蜂窝移动无线通信系统的多址访问协议进行了研究。研究了ＰＲＭＡ系统中同时存在高、低优先级话音终端的Ｐｐｒｍａ协议的性能，提出了话音终端具有自适应重发许可概率的Ａｐｒｍａ协议。利用系统仿真技术对协议的性能进行了估计。

The multiple access protocol of the third generation microcelular wireless communication systems is researched in this paper.The performance of priority packet reservation multiple access(Pprma)joint high and low priority voice terminals is discussed. Adaptive packet reservation multiple access (Aprma)is proposed. System simulation is carried out and performance of Aprma is evaluated.
