下行波束形成与上行Rake接收机的联合处理技术

A joint treatment technique for down link beamforming and up link Rake receiver

本文基于CDMA移动通信系统中上下行信道的双向共性特征 ,通过上行接收信号子空间分解 ,确定下行发射信号子空间特征 ,从而提出一种下行最优发射波束形成与上行空间Rake接收机联合处理技术。通过计算机仿真进一步验证了本文提出的联合处理技术的有效性。

This paper stands on the fact that bidirectional commonalty holds between uplink and down link channel state in CDMA mobile communication Down link signal subspace state is defined by up link signal sub space decomposition,then a joint treatment technique for down link beam forming and up link Rake is proposed The performance of algorithms proposed is illustrated by computer simulation
