Mutual Coupling-Aware Beamforming in Multi-User Continuous Aperture Array Systems
A kernel-approximation WMMSE algorithm is derived for mutual-coupling-aware beamforming in CAPA multi-user systems, yielding closed-form solutions via wavenumber Fourier transforms and showing higher degrees of freedom in close-proximity CAPA-to-CAPA MIMO.
