针对微蜂窝移动的通信，提出了一种新的时分复用下基于帧的分组预约多址（F-PRMA）协议，并建立了仿真模型。通过大量的仿真，分析了不同语音业务负载下多址接入协议的分组丢弃概率P/sub drop/、信道容量M/sub 0.01/和系统吞吐量/spl ρ/等性能，研究了系统参数和协议变量对协议效率的影响。研究结果表明，F-PRMA协议在时分复用（M/sub 0.01/=36，多址接入增益/spl eta/=1.6）下具有很高的效率，在频分复用下与原PRMA协议的性能几乎相同。
A new frame-based packet reservation multiple access (F-PRMA) protocol under time-division duplexing is proposed for microcellular mobile communications, the simulation model of which is built. By extensive simulations, the performances of the multiple access protocol including packet dropping probability P/sub drop/, channel capacity M/sub 0.01/ and system throughput /spl rho/ are analyzed under different speech service loads, and the effects of the system parameters and protocol variables on the efficiency of the protocol are examined throughout. The result of the study shows that the F-PRMA protocol is highly efficient under time-division duplexing (M/sub 0.01/=36, multiple access gain /spl eta/=1.6), and has almost the same performance as the original PRMA protocol under frequency-division duplexing.
