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…
Quadrature Over-the-Air-Computing for Multimodal Dual-Stream Signal Processing
Hyeon Seok Rou, Kengo Ando, Giuseppe Thadeu Freitas de Abreu +1
We propose a novel quadrature over-the-air computing (Q-OTAC) framework that enables the simultaneously computation of two independent functions and/or data stream within a single…
A Flexible Design Framework for Integrated Communication and Computing Receivers
Kuranage Roche Rayan Ranasinghe, Kengo Ando, Hyeon Seok Rou +4
We propose a framework to design integrated communication and computing (ICC) receivers capable of simultaneously detecting data symbols and performing over-the-air computing (AirC…
From Theory to Reality: A Design Framework for Integrated Communication and Computing Receivers
Kuranage Roche Rayan Ranasinghe, Kengo Ando, Giuseppe Thadeu Freitas de Abreu
We propose a novel flexible and scalable framework to design integrated communication and computing (ICC) -- a.k.a. over-the-air computing (AirComp)-- receivers. To elaborate, whil…
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…
Blind Bistatic Radar Parameter Estimation for AFDM Systems in Doubly-Dispersive Channels
Kuranage Roche Rayan Ranasinghe, Kengo Ando, Hyeon Seok Rou +2
We propose a novel method for blind bistatic radar parameter estimation (RPE), which enables integrated sensing and communications (ISAC) by allowing passive (receive) base station…
