Robust Symbol Detection in Overloaded NOMA Systems
Hiroki Iimori, Giuseppe Thadeu Freitas de Abreu, Hara Takanori +5
We present a framework for the design of low-complexity and high-performance receivers for multidimensional overloaded NOMA systems. The framework is built upon a novel compressive…

A Frame-Theoretic Scheme for Robust Millimeter Wave Channel Estimation
Razvan-Andrei Stoica, Giuseppe Thadeu Freitas de Abreu, Hiroki Iimori
We propose a new scheme for the robust estimation of the millimeter wave (mmWave) channel. Our approach is based on a sparse formulation of the channel estimation problem coupled w…
