Abstract :
A soft antenna selection (SAS) method is basically implemented by a linear network (LN) which is located in RF domain of multiple-input multiple-output (MIMO) systems. In this paper, we find the optimum receiver SAS structure which maximizes the signal to interference-plus-noise ratio (SINR) gain for the diversity transmission in an interference channel. The optimization is applied for two practical cases of transmitters either with or without channel state information. A two-dimensional (2D) directive model is employed to realize the interference effect. A Rician channel model is used for computer simulation. The simulation results show the optimum SAS achieving the performance of the full-complexity MIMO, i.e. a MIMO system with the same number of antenna terminals and RF chains.
