Abstract

The problem of robust beamformer design for mobile communications applications in the presence of moving co-channel sources is addressed. A generalization of the optimum beamformer based on a statistical model accounting for source movement is proposed. The new method is easily implemented and is shown to offer dramatic improvements over conventional optimum beamforming for moving sources under a variety of operating conditions
