Beamspace adaptive beamforming based on principle component analysis
Lei Yu, Wei Liu, R.J. Langley · 2008
A novel adaptive beamforming method is proposed without the knowledge of the direction of arrival of the signal of interest. It is a combination of the traditional beamspace processing method and a recently proposed technique called “Domain Weighted Principal Component Analysis (DW-PCA)” and can be applied to the case where the signal of interest is stronger than the interfering signals in both single-path and multi-path environments. Its effectiveness is verified by simulation results.
