摘要

本文研究了支持综合业务的CDMA系统中基站接收机的干扰功率变化。结果表明，即使在完美的功率控制条件下，共享信道中多速率/业务用户的支持也会导致干扰功率的显著变化，从而导致业务的不可预测交付。给出了一个集成语音和数据系统的数值结果。当功率因数(比特率和误码率的函数)从1增加到10时，多媒体业务泊松分布下12扇区小区的干扰功率归一化标准差增加约75%。

Interference power variation in integrated services CDMA networks: a single cell analysis

In this paper, interference power variation at a base station receiver in a CDMA system that supports integrated services is investigated. It is demonstrated that even under perfect power control conditions, the supporting of multi-rate/service users in shared channel will cause the interference power to vary significantly causing unpredicted delivery for services. Numerical results are presented in an integrated voice and data system. When the power factor (which is a function of bit rate and bit error rate) is increased from 1 to 10, the normalized standard deviation of interference power increases approximately 75% in a 12-sector cell under Poisson distribution of multimedia traffic.
