Constrained Optimization Models for Integrated Space-Time Interference Suppression in CDMA Systems and Their Neural Network Implementation
Rongfang Song · Dianzi xuebao · 2001
The constrained optimization models for integrated space-time interference suppression in CDMA systems are proposed in this paper.The models combine smart antenna and RAKE receiver together,and mitigate multiuser access interference (MAI) and interchip interference (ICI).The conditions of zero-forcing equalization are derived.Neural network implementation of the models is also studied.Finally,the performance of the suppressors is investigated.
