Fast Adaptive Beamforming for Coherent Interference Cancellation Using Forward/Backward Correlations
Yang-Ho Choi · IEICE Transactions on Communications · 2009
An adaptive beamforming method for the rejection of coherent interference signals is presented which exploits forward and backward correlations. The proposed method, in which the effective degree of freedom of the beamformer is increased by virtue of its use of both types of correlation, can cancel more coherent interference signals and provide better performance than the existing one that uses the forward correlation only.
