Performance Analysis of Spatial Modulation over Correlated Fading Channels

We present a general upper bounding framework for the average bit error probability of spatial modulation over correlated Rayleigh and Rician channels. The proposed approach provides a closed form upper bound for correlated Rayleigh fading conditions whereas for correlated Rician channels it leads to the numerical evaluation of a single integral formula. The framework is applicable to a general class of linear modulation alphabets and any number of transmit/receive antennas. Theoretical derivations are validated via simulation results.
