On the performance of Space Shift Keying MIMO systems over correlated Rician fading channels

Abstract

In this paper, we study the performance of Space Shift Keying (SSK) modulation for a generic Multiple-Input-Multiple-Output (MIMO) wireless system over correlated Rician fading channels. In particular, we propose a very general framework for computing the Average Bit Error Probability (ABEP) of SSK-MIMO systems over a generic Rician fading channel with arbitrary correlation and channel parameters. The framework relies upon the Moschopoulos method. We will show that it is exact for MIMO systems with two transmit-antennas and arbitrary receive-antennas, while an asymptotically-tight upper-bound is proposed to handle the system setup with an arbitrary number of transmit-antennas. Analytical frameworks and theoretical findings will be substantiated via Monte Carlo simulations for various system setups.
