The reason for this is due to inter channel Block Code (STBC), Vertical Bell Lab Layered Space Time (V- interference (ICI), InterAntenna Synchronization (IAS)and BLAST) etc, a spatial modulation (SM) scheme with multiple multiple radio frequency chains. To overcome this, Space active antennas, named as Multiple Active Spatial Modulation Time Block Code (STBC) uses the potential of multiple (MA-SM) is introduced. A syste
