摘要

研究了蜂窝CDMA下行链路的软切换和分组传输调度问题。为了保证软切换中各连接所要求的信干扰比，首先建立了功率分配规律。在此基础上，提出了话音和数据综合业务的分组传输调度。仿真结果表明，基于功率分配规律提出的分组调度方案能够显著提高语音连接的可靠性，增加系统容量，实现较高的数据包传输吞吐量。

Effect of soft handoff on packet transmissions in cellular CDMA downlinks

Soft handoff and packet transmission scheduling are studied for cellular CDMA downlinks. A power distribution law is developed first in order to guarantee the required signal-to-interference ratio for each connection in soft handoff. Based on this, packet transmission scheduling for integrated voice and data traffic is proposed. Simulation results show that the proposed packet scheduling scheme using the derived power distribution law can significantly improve the voice connection reliability, increase the system capacity, and achieve high data packet transmission throughput.
