摘要

提出了一种新型波束形成器，用于同时接收多个卫星信号，同时抑制干扰。该方案包括三个阶段。首先利用奇异值分解技术构造去除干扰的变换;其次，基于仅由卫星信号和加性噪声组成的变换数据进行特征波束形成，为每颗卫星产生多波束;最后，将权重向量投影到信号加噪声子空间中，以获得更高的输出信噪比。数值算例验证了该方法的有效性。

A novel beamformer with multiple signal reception for GPS receivers

A novel beamformer is proposed for simultaneous reception of multiple satellite signals, while rejecting interference. The scheme consists of three stages. Firstly a singular value decomposition technique is utilized to construct a transformation for removing interferers. Secondly, an eigen-based beam forming is performed based on the transformed data consisting of only satellite signals and additive noise to produce multiple beams for each satellite. Finally, the weight vector is projected onto signal-plus-noise subspace to achieve a higher output SINR. Numerical examples confirm the efficacy of the proposed scheme.
