摘要

为了在非均匀通信量条件下增强系统容量和提高系统效率，对CDMA蜂窝系统进行了频域、时域和空域的划分研究。本文描述了一种小区分块CDMA系统，该系统将时隙分配给小区内的若干子区域。这些时隙是根据相邻单元的不同模式分配的。在流量均匀分布的情况下，下行系统容量增长约15%。利用热点模型评价表明，根据流量分布自适应划分小区后，下行链路质量得到改善。

Downlink performance of cell-partitioned CDMA cellular systems with time-slot assignment

There have been studies to divide CDMA cellular systems in the frequency, time, and space domains to enhance the system capacity and improve the system efficiency under nonuniform traffic conditions. This paper describes a cell-partitioned CDMA system in which the time slots are assigned to several subareas in a cell. These time slots are assigned according to different patterns in the adjacent cells. The downlink system capacity increased by about 15% under a uniform traffic distribution. Evaluation using a hot-spot model showed that the downlink quality improved when cells were adaptively partitioned according to the traffic distribution.
