Abstract

Abstract : In this study, a wireless powered dual‐hop relay system, which consists of a source, a destination and a relay that is equipped with N R ( N R > 1 ) receiving antennas and finite energy storage, is considered. Antenna selection scheme is employed for the relay to harvest energy from the received signals, under which the L R ( 0 < L R ≤ N R ) strongest received signals are combined for information processing and the other L Z = N R − L R copies of signals are used for energy harvesting. Considering Nakagami‐ m fading scenarios, the authors first derive the closed‐form expressions for the probability density function and the cumulative distribution function of the signal‐to‐noise ratio with generalised selection combining (GSC), and then the exact and asymptotic analytical expressions for outage probability are derived, respectively. Finally, simulation results are presented to verify the proposed analysis model.
