基于数据预处理的解相关波束赋形方法

A Decorrelated Beamforming Method Based on Preprocessing in Data Domain

在智能天线波束赋形技术中,当存在相关干扰时,一般的波束赋形算法不能有效地抑制相关干扰,引起期望信号相消的现象。提出了一种先在数据域实施数据预处理,再进行波束赋形的解相关的波束赋形方法,该方法在抑制相关干扰的同时,能在期望方向形成最大波束。并使用Matlab仿真对所提出方法的有效性进行了验证。

The general beamforming algorithms can not effectively restrain correlative interference, as a result, the desired signals are elirnated each other in the presence of correlative interference. A robust decorrelated method is presented. First, preprocessing in data domain is adopted for interference cancellation, then beamforming is performed. This method can not only suppress the correlative interference, but also form the biggest beam on the desired direction. The novel method＇s efficiency has been approved by using Matlab.
