CDMA系统软切换性能分析

Performance Analysis of Soft Handoff in CDMA Systems

在CDMA系统中,软切换发生在软切换区域。因此,对软切换分析过程中,软切换区域变得非常重要。本文提出了一种新的软切换分析模型,在模型考虑了相邻小区的重叠区(即软切换区域),还有切换尝试率、信道占用时间和移动台速度。本文中,在不同的移动台速度和软切换区域大小条件下,对软切换性能进行分析。

The soft handoff is happened in soft handoff region （SR）. Therefore, there is import of the SR size on handoff process. The authors study the performance of soft handoff in CDMA systems where is based on the square model. The effects of SR size, MS＇s speed and call arrival rate on call blocking probability are investigated. The paper analyses performance of soft handoff within different of SR size and MS＇s speed in the CDMA systems.
