Abstract
In this paper, the performance of space shift keying (SSK) modulation in a wireless-powered communication network (WPCN) is analysed with selection combining based on generalized Euclidean distance at the receiver. The network considered here is with multiple number of transmitting antennas and multiple number of receiving antennas operates under Rayleigh fading. Based on the Euclidean distance between the SSK modulation constellation points, this scheme selects any number of antennas out of $$N_a$$ receiving antennas. Selecting one or $$N_r$$ ( $$N_r<N_a$$ ) number of receiving antennas with energy harvesting, the system performance will improve and the receiver complexity as well as the number of radio frequency (RF) chains can be reduced. A closed form expression for the average bit error probability (ABEP) is derived for two transmitting antennas and $$N_a$$ receiving antennas with WPCN using SSK modulation. The numerical results and simulation results are presented to illustrate the energy harvesting on system performance.
