Abstract :
In this paper, we present a new scheme named advanced spatial modulation for multiple input multiple output (MIMO) systems. Advanced spatial modulation achieves more spectral efficiency than ordinary spatial modulation with using power divider and set the phase of active transmit antennas. Using Power divider enable us to have more than one active antenna in a time slot with only one RF-chain in transmitter. Additionally, we can allocate more spatial bits with map information bits into the phase of the transmit antenna. Then, the performance of the proposed system is simulated and is compared with ordinary spatial modulation and some MIMO techniques such as orthogonal space time block code and V-BLAST.
