摘要

我們提出一個有限狀態馬可夫模型去分析直接序列分碼多工/非同步阿囉哈網路對兩個使用群的吞吐量在行動裝置上，先前的論文都是在直接序列分碼多工/非同步阿囉哈網路在雷利衰減有限馬可夫通道下並沒有考慮將使用者分成兩個使用群討論跟應用存取控制，本篇所提出的直接序列分碼多工/非同步啊囉哈無線網路對兩個使用群應用存取控制在高優先序的使用群在高封包時間訊息到達率可以維持最大的吞吐量。

We propose the finite-state Markov channel (FSMC) model to the throughput analysis of DS CDMA/unslotted ALOHA for two user classes wireless networks in the mobile environment. The previous papers in DS CDMA/unslotted ALOHA networks in Rayleigh fading FSMC do not consider dividing system users to two user classes and access control. The proposed DS CDMA/unslotted ALOHA wireless networks for two user classes with access control can maintain maximum throughput for the high priority user class under high message arrival per packet duration.
