摘要

以2.4 GHz频段的多媒体室内无线系统为例，分析了多径特性对无线DS CDMA系统性能的影响。系统的下行性能是根据误码率和用户容量来评估的。比较了两种分析模型和一种基于实测剖面的经验模型的结果。一种分析模型假设路径增益独立同分布，另一种模型假设路径增益独立指数分布。用解析通道模型得到的结果比用实测通道得到的结果更为悲观。

Performance analysis of a DS CDMA system using measured delay profiles in an indoor environment

The effect of multipath characteristics on the performance of a wireless DS CDMA system has been analysed by considering a specific wireless indoor system for multimedia applications in the 2.4 GHz band. The downlink performance of the system is evaluated in terms of the bit error rate and user capacity. The results are compared for two analytical channel models and one empirical model based on measured profiles. One analytical model assumes independent identically distributed path gains, the other one assumes independent exponentially distributed path gains. The results obtained with the analytical channel models show more pessimistic results than with the measured channels.
