摘要:Distributed Spatial modulation (DSM) is a recently developed multiple-input-multiple-output (MIMO)techniquethat uses multiple transmit antennas in a innovative fashion. In SM, a group of information bits ismapped intotwo constellations: a signal constellation based on modulation scheme, and a spatial constellationto encode the index ofa transmit antenna.DSM, multiple relays form a virtual antenna array and assist a source to transmit its informationto adestination by applying SM in a distributed manner. The source broadcasts its signal, which is independentlydemodulated by all the relays. Each of the relays then divides the received data in two parts: the first part is used todecide which one of the relays will be active, and the other part decides what data it will transmit to the destination. Ananalytical expression for symbol error probability is derived for DSM in independent and identically distributedRayleigh fading channels.
