Title: Precoded Spatial Modulation for Robustness against Correlated Rician Fading
Abstract: We present a precoding approach for spatial modulation (SM) to provide robustness against both the Rician fading effects and also spatial correlations among transmit antennas. This approach, based on phase-rotation and/or amplitude scaling of the transmitted symbols according to the active transmit antenna, can be implemented while keeping the average power budget and without any explicit knowledge of the channel state information at the transmitter. The optimum values of the precoding coefficients are determined so as to minimize the asymptotic average bit-error rate (ABER). Both theoretical analysis and simulation results indicate significant performance improvements even in the case of heavily correlated transmit antennas.
