Modulus Zero-Forcing Detection for MIMO Channels

Hu, Sha LU and Rusek, Fredrik LU (2019) 2018 IEEE Global Communications Conference, GLOBECOM 2018
Abstract

We propose a modulus based zero-forcing (MZF) detector for multi-input multi-output (MIMO) channels. Traditionally, a ZF detector nulls out interference from other layers when detecting a certain layer. While this is conceptually simple, it can result in considerable noise-enhancement. In many communication systems, finite alphabets such as M quadrature-amplitude-modulation (QAM) are used, which comprises \sqrt{M} pulse-amplitude- modulation (PAM) symbols in both the real and imaginary components. With finite alphabets, one feasible way to improve ZF detection is to allow controllable interference that can be removed away by a modulus operation.
