Abstract

In mobile communication systems, in order to extract the desired signal while suppressing the interference and noise, array beamforming techniques are usually employed. We propose a blind adaptive beamformer against co-channel interference and noise. The proposed method utilizes the cyclostationary properties of the communication signal, and a simple and efficient computational load. We performed computer simulations to compare the performance between the proposed method and the conventional method
