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…
Robust Reduced-Rank Adaptive Processing Based on Parallel Subgradient Projection and Krylov Subspace Techniques
R. C. de Lamare, M. Yukawa, I. Yamada
In this paper, we propose a novel reduced-rank adaptive filtering algorithm by blending the idea of the Krylov subspace methods with the set-theoretic adaptive filtering framework.…
Lp-Regularized Least Squares (0<p<1) and Critical Path
Masahiro Yukawa, Shun-ichi Amari
The least squares problem is formulated in terms of Lp quasi-norm regularization (0<p<1). Two formulations are considered: (i) an Lp-constrained optimization and (ii) an Lp-penaliz…
Coordinated Beamforming with Relaxed Zero Forcing: The Sequential Orthogonal Projection Combining Method and Rate Control
Juho Park, Gilwon Lee, Youngchul Sung +1
In this paper, coordinated beamforming based on relaxed zero forcing (RZF) for K transmitter-receiver pair multiple-input single-output (MISO) and multiple-input multiple-output (M…
