Abstract
We analyze the effect of distributed switch and stay combining (DSSC) technique and imperfect channel state information (CSI) in the scenario, where the communication between the source and the destination is conducted through either the direct transmission or with the help of the best relay among K full-duplex energy harvesting relays by using partial relay selection. To activate such communication, at the destination, we apply DSSC technique, which is considered as an effective method to achieve spatial diversity in a distributed manner with low processing complexity and compatibility to resource-constrained wireless networks. Considering two popular relaying protocols, i.e., decode-and-forward (DF) and amplify-and-forward (AF), the performance analysis in terms of outage probability (OP) is carried out. Numerical results show that imperfect CSI has a negative impact on system performance. Besides that, our DSSC-full duplex selection relaying (FDSSCSR) system achieves a better performance in terms of outage probability than that of the DSSC-half duplex selection relaying (HDSSCSR) and the full duplex/half duplex dual hop relaying with partial relay selection (FD/HDDRPRS) systems. Simulation results are conducted to verify the correctness of our analysis.
