Abstract
In this paper, the performance of an energy harvesting based partial relay selection (PRS) cooperative system with transmit antenna selection (TAS) and outdated channel state information (CSI) is presented. The system dual-hops links are assumed to follow Rayleigh distribution and the relay selection is based on outdated CSI of the first link. The amplified-and-forward (AF) relay nodes are equipped with a single receive antenna and multiple transmit antenna while the destination utilized multiple receive antenna. Consequently, the cooperative system then employs the TAS technique at the relay nodes and maximum ratio combining (MRC) scheme is used at the destination. Based on this, the analytical closed-form expressions for the outage probability and throughput in delay-limited transmission mode are derived. The results demonstrated that the energy harvesting time, relay distance, channel correlation coefficient, the number of relay transmit antennas and destination received antenna have significant impact on the system performance. The accuracy of the derived expressions is validated by Monte-carol simulation.
