Generalised loading algorithm for adaptive beamforming in ULAs

A new method for adaptive beamforming in uniform linear arrays (ULAs) is introduced. The proposed method is based on generalised loading of the covariance matrix of the data vector received by the array. The covariance matrix is loaded with a Hermitian matrix which is chosen to shape the directional response of the array. Simulation results show that the proposed approach offers better handling of mismatches between presumed and actual array steering vectors. It produces output signal‐to‐interference‐plus‐noise ratio values higher than some well‐known approaches in the literature with much less complexity.
