Performance analysis of cooperative wireless sensor network with index-based modulation

Spatial modulation (SM) emerges as a potential technique for next generation wireless networks. Enhanced spectral efficiency and equitable system complexity led SM to various innovations. In SM only one radio-frequency chain is active during the transmission of the signal. The information is carried...
