An Analytical Derivation of the Symbol Error Rate of Spatial Modulation in Correlated Rayleigh Fading Channels

The need for high-rate wireless data transmission with efficient spectrum usage has sparked the development of multiple-input multiple-output (MIMO) systems using antenna arrays at the transmitter and receiver side. Spatial modulation is a new spatial multiplexing scheme promising high data rates. Its performance is affected by certain impairments of the radio channel. The effects of transmitter-side spatial correlation on the modulation scheme are studied here, both analytically and with Monte Carlo simulation methods. A new scheme for the analytical calculation of the symbol error rate of spatial modulation is proposed.
