| 摘 要： | 蜂窝数字分组数据（ＣＤＰＤ）是利用现有的模拟蜂窝电话网来传输数据的一种新技术，它有两种信道分配方案，固定信道方案和跳频方案。立足于ＭＡＣ（ 媒质接入控制） 层，通过仿真和计算，对ＭＤＢＳ（ 移动数据基站） 和ＭＥＳ（ 移动终端系统） 之间的数据传输性能进行了分析，得到了数据吞吐量、平均时延以及由于传输数据而引起的话务量损失值

| Abstract: | The cellular digital packet data (CDPD) is a system which borrows idle radio channels from the existing cellular mobile telephone network for packet data transmission.There are two channel assignment algorithms,dedicated channel algorithm and frequency hopping algorithm.In this paper,we simulate the procedure in CDPD MAC layer,acquire the data throughput,the average delay and the voice traffic loss,and analyze the data transmission performance of both algorithms. |
