Abstract

In this letter, the performance of space shift keying (SSK) modulation for multiple-input multiple-output (MIMO) systems with imperfect channel knowledge and in the presence of co-channel interference (CCI) and Rayleigh fading is investigated. In particular, closed-form expressions of the average bit error probability (ABEP) for an arbitrary number of transmit antennas are obtained. To gain further insight on the system performance, simple asymptotic expressions of the ABEP for high Signal-to-Noise Ratio (SNR) are computed, which provide information on the achievable diversity order and coding gain. Numerical results are shown to substantiate mathematical frameworks and findings.
