Spatial Modulation in Rayleigh fading channel

  • MathsCodes

Spatial modulation was proposed few years back to achieve a higher data rate and solving the major problems in multiple-input multiple-output (MIMO) systems. This was made possible just by using spatial dimension to convey information together with the transmitted signal. However, the spatial dimension of the constellation dimension is also used to select the active antenna per transmission instant. Thus, made the use of single antenna per transmission instant possible resulting in the use of single RF chain. This eliminate the need for antenna synchronization since only one antenna is active at a time so the antennas don’t need to synchronize before transmission. Also this eliminate inter-channel interference and inter-symbol interference since only one symbol is transmitted at each time slot.
