| 摘 要： | 本文对具有多重码的预约Slotted ALOHA协议进行了性能分析。它是基于帧的协议且在一个时隙内有多重码可用来传输分组信息。文中利用离散时间，离散状态和Markov链来分析一个小区上行链路的话音分组吞吐量和数据分组延时性能，并提出了两种改进碰撞解决的方法，得到了较好的系统特性。

| Abstract: | The performance of the protocol of reservation slotted ALOHA with multi-code is considered. It is a frame-based protocol with multi-code transmissions in a slot. A discrete-time, discrete-state Markov chain is used to evaluate the up link performance of the voice packet throughput and data packet transmission delay in a cell. To solve the collision problem two access permission control schemes are proposed. The better system per- formance can be achieved with access permission control methods according to offered traffic. |
