Outage probability of MIMO relaying full-duplex system with wireless information and power transfer

In this paper, we consider a full duplex relaying multi input multi output (MIMO) system where the relay has no fixed energy supply but replenishes energy from radio frequency (RF) signals transmitted from source. At the transmitter, transmit antenna selection (TAS) and maximal ratio transmission (MRT) are employed. Whereas, at the second hop, both selection combining (SC) and maximal ratio combining (MRC) techniques are used. In addition, the decode-and-forward relaying protocol is applied. We derive the expressions of outage probability (OP) of the simultaneous information and energy transfer in Rayleigh fading relay channel. Numerical results are presented to demonstrate the validity of our analysis and to show the advantages of full duplex relaying MIMO system.
