ABEP of SSK with SWIPT at Relay and Generalised Selection Combining at the Destination over Rayleigh Fading

Abstract

A cooperative communication system with space shift keying (SSK) modulation and simultaneous wireless information and power transfer (SWIPT) scheme is analyzed over Rayleigh fading channel. SSK is a simple modulation technique that enhances data rate, minimize inter-channel interference, inter-antenna synchronization, and number of radio frequency chains whereas SWIPT extends battery life at the relays. Average bit error probability (ABEP) using partial relay selection and generalised selection combining (GSC) schemes at the receiver are investigated for Rayleigh fading channels. ABEP expression is derived with single amplify and forward (AF) relay selection, from multiple relays, and using selection combining of signals from multiple antennas. Numerical and computer simulation results are presented with the discussion.
