摘要

本文研究了软切换微分集增益对UMTS系统性能的影响。首先，通过链路层模拟，根据平均Eb/N0要求的降低来测量微分集增益。在对这种效应进行建模后，通过一些系统级仿真，我们显示了这种通常被忽视的增益对UMTS整体性能的高影响，表明下行链路软切换不仅提高了服务质量，而且提高了系统的整体容量

Evaluation of Soft Handover Micro Diversity Gain on the UMTS System Capacity and QoS

In this paper the impact of the soft handover micro diversity gain on the UMTS system performance is investigated. First, by means of link layer simulations the micro diversity gain is measured in terms of reduction of the average Eb/N0 requirement. After modelling this effect, by some system level simulations we show the high influence of this usually neglected gain in the overall performance of UMTS, demonstrating that in downlink soft handover improves not only the quality of service but also the overall system capacity
