Relaxed Zero-Forcing Beamformer under Temporally-Correlated Interference
Takehiro Kono, Masahiro Yukawa, Tomasz Piotrowski
The relaxed zero-forcing (RZF) beamformer is a quadratically-and-linearly constrained minimum variance beamformer. The central question addressed in this paper is whether RZF perfo…
