Multibit Quantized Precoding for MU-mMIMO
Getuar Rexhepi, Shreesal Shrestha, Christoph Studer +1
We propose a novel multibit quantized precoding method for the downlink of multi-user massive MIMO systems with low-resolution digital-to-analog converters. The new method, termed…
Low-complexity Leakage Minimization Beamforming for Large-scale Multi-user Cell-Free Massive MIMO
Iván Alexander Morales Sandoval, Marko Fidanovski, Getuar Rexhepi +2
We propose a low-complexity beamforming (BF) scheme for secrecy-rate maximization in multi-user (MU) cell-free massive multiple-input multiple-output (CF-mMIMO) systems, where legi…
Low Rank Tensor Completion via Adaptive ADMM
Niclas Führling, Getuar Rexhepi, Giuseppe Thadeu Freitas de Abreu
We consider a novel algorithm, for the completion of partially observed low-rank tensors, as a generalization of matrix completion. The proposed low-rank tensor completion (TC) met…
Discrete Aware Matrix Completion via Convexized -Norm Approximation
Niclas Führling, Kengo Ando, Giuseppe Thadeu Freitas de Abreu +2
We consider a novel algorithm, for the completion of partially observed low-rank matrices in a structured setting where each entry can be chosen from a finite discrete alphabet set…
