Spatial Modulation (SM) is a recently proposed joint coding and modulation scheme for Multiple-Input - Multiple-Output (MIMO) wireless systems, which is receiving a growing interest. SM is used in wireless systems, which can offer good data rates and error performance with a moderately low system complexity. Adaptive modulation schemes for fading channels are usually required to fulfill certain long-term average BER targets. Performance of SSK modulation increases for increasing values of the target bit rate and of the number of antennas at the receiver. This modulation has the same robustness to channel estimation errors as conventional modulation schemes.
