Abstract

Ahypercomplex variantof Capon beamformer, called biquaternion Capon (BQ-Capon), is herein proposed for signal strengthening with four-component vector-sensor arrays. This BQ-Capon beamformer extracts the signal-of-interest (SOI) while rejecting interferences plus noisein amultipleinput-multiple-output (MIMO) fashion. Simulation results show that BQ-Capon beamformer outperforms the standard long-vector counterpart in convergence and sensitivity to mismatch in SOI steering vector.
