Abstract

In this paper, we find the optimum soft antenna selection (SAS) which maximizes the mutual information for the multiple-input multiple-output (MIMO) spatial multiplexing transmission in an interference channel. In this optimization problem, a 2-Dimensional (2D) directive interference model is used. We first find an optimal solution for SAS without applying any constraint on it and then propose a sub-optimal solution for the case when a phase-shift-only passive linear network (PLN) is used to implement the SAS method. Moreover, we compare the performance of the SAS method with a full-complexity MIMO system in the presence of above modeled interference through a simulation study.
