Abstract

This paper describes a blind beamforming algorithm based on maximum SINR criterion applied to the reverse link of the W-CDMA system. The maximum SINR weight vector is derived by exploiting the separation of the frequency band of the desired signal from the frequency band of the interference and noise after a despreading operation on the received CDMA signal. Thus, the algorithm applies the concept of the frequency gating to the CDMA beamforming. We call this algorithm a code gated algorithm or CGA to distinguish the use of CDMA spreading code in separating the desired signal from the interference and noise.

编码门控算法:一种适用于宽带CDMA系统的盲自适应天线阵列波束形成方案

介绍了一种应用于W-CDMA系统反向链路的基于最大信噪比准则的盲波束形成算法。最大SINR权向量是通过利用期望信号的频带与干扰和噪声的频带的分离，在对接收的CDMA信号进行扩频操作后推导出来的。因此，该算法将频率门控的概念应用于CDMA波束形成。我们将该算法称为码门控算法或CGA，以区别于使用CDMA扩频码将期望信号与干扰和噪声分离。
