On the Performance of Spatial Modulation for MIMO Communication

B.Revathi, P.Poonguzhali, A.Angelin, C.Arunachalaperumal

Spatial Modulation (SM) provides many advantages when compared to other conventional Multiple Input Multiple Output (MIMO) schemes in which multiple antenna transmit simultaneously. In SM only one antenna will be active during data transmission. This completely eliminates Inter Channel Interference (ICI) and reduces decoding complexity. In other coding techniques coding and modulation is done separately, but in Trellis Coded modulation (TCM), coding and modulation are combined together. In this paper the performance of SM-TC is compared to the performance of other techniques like Space Shift Keying (SSK), Spatial Modulation and Vertical Bell Labs Layered space time (VBLAST). SM-TC achieves better error performance when compared to previous MIMO techniques with minimum decoding complexity
