Capacity Maximizing Adaptive Time-Switching Protocol for Energy Harvesting Full-Duplex Relaying Network over Rayleigh Fading Channel

This paper studies a decode-and-forward (DF) full-duplex cooperative relaying network, whereas one transmitter S transmits information to one receiver D via the help of a relay R. In particular, the transmitter can simultaneously transmit energy and information (SWIPT) to relay R using time-switching (TS) method. Then, relay R can utilize the harvested energy to transfer information to the receiver D. Based on the proposed system model, we derive the mathematical expressions for the system capacity for the proposed non-adaptive TS (NATSP) and adaptive TS protocols (ATSP). Next, the Monte Carlo simulations are executed to corroborate the exactness of the analysis compared to the numerical results. Both numerical and analytical results show the superiority of ATSP over NATSP.This is an Open Access article distributed under the terms of the Creative Commons Attribution License (http://creativecommons.org/licenses/by/4.0/), which permits unrestricted use, distribution, and reproduction in any medium provided the original work is properly cited.
