摘要: 提出了在CDMA系统中综合考虑干扰删除、智能天线和功率控制的算法,即使干扰信号与有用信号以同样的角度到达天线,干扰信号也能够被删除。同时考虑功率控制,在满足信噪比要求时,所有用户发射的总功率最小。

关键词: CDMA系统, 功率控制, 智能天线, 干扰删除

Abstract: A scheme combined with interference cancelling, adaptive antenna and power control is proposed. It can mitigate multiple access interference even if interference signal arrives at antenna array at the same angle with the desired signal. Combined with power control, the total power expended by all users in the system is saved.

Key words: CDMA system, power control, adaptive antenna, interference cancelling
