摘要: 提出一种面向CDMA蜂窝移动通信系统的支持多种业务的媒体接入控制协议OSSS/PRMA.该协议引入过载控制信号,有效地降低了随机接入的碰撞率,提高了系统的性能.仿真结果表明,与CDMA/PRMA协议相比,该协议的数据分组平均时延、语音分组丢失率和信道利用率都有较大改善.

Abstract: A joint overload-signal spread-spectrum/packet reservation multiple access (OSSS/PRMA) protocol for the uplink channel in CDMA communication system is proposed. We introduce the overload signal in our protocol, which reduce the probability of the collision. The simulation results show that the data packet delay and voice packet dropping probability have been greatly improved compared with CDMA/PRMA protocol with adaptive permission probability control.
