摘要
本文提出了CDMA系统中抑制多址干扰 (MAI)和码片间干扰 (ICI)的利用智能天线和RAKE接收相结合的时空综合干扰抑制器的约束优化模型 ,导出了迫零均衡条件 ,探讨了其神经网络实现问题 。
The constrained optimization models for integrated space-time interference suppression in CDMA systems are proposed. 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.
