    Abstract

    When using filter bank based multicarrier orthogonal quadrature amplitude modulation (FBMC/OQAM) techniques in a multiple-input multiple-output (MIMO) environment, its difficulty of dealing with inter-symbol interference (ISI) and intercarrier interference (ICI) is further exacerbated by the presence of spatial interference. In this paper, we describe the transfer functions (including al temporal and spatial interference terms) by polynomial matrices. The equalisation of this system can then be performed by a proposed polynomial matrix pseudo-inverse. Some numerical examples for this technique are presented.
