摘要：Spatial modulation (SM) is a recently developed Multiple-Input-Multiple-Output (MIMO) technique
that uses multiple transmit antennas in an innovative fashion. In SM, a group of information bits is mapped into two
constellations: a signal constellation based on modulation scheme, and a spatial constellation to encode the index of a
transmit antenna. To overcome these problems, Distributed Spatial Modulation (DSM) offers a promising solution. In
DSM, multiple relays form a virtual antenna array and assist a source to transmit its information to a destination by
applying SM in a distributed manner. The source broadcasts its signal, which is independently demodulated by all the
relays. Each of the relays then divides the received data into two parts: the first part is used to decide which one of the
relays will be active, and the other part decides what data it will transmit to the destination. An analytical expression for
symbol error probability is derived for DSM in independent and identically distributed (i.i.d.) Rayleigh fading channels.
