Impacts of Nonlinear Energy Harvesting and Residual Self-Interference on the Performance of Full-Duplex Decode-and-Forward Relay System

In this paper, we investigate the usage of a nonlinear energy harvester at full-duplex (FD) relay, which can harvest from radio frequency (RF) signals transmitted source. We mathematically derive exact closed-form expressions outage probability (OP), throughput, and average symbol error rate (ASER) harvester-wireless information power transfer-FD relaying (N-WIPT-FDR) system over Rayleigh fading channels. Unlike linear harvester, results in more computational complexity. Furthermore, it makes floor happen faster even when self-interference cancellation (SIC) techniques are effectively applied due to saturation threshold harvester. The combination characteristic residual (RSI) has significant impacts on OP, ASER considered N-WIPT-FDR system. On other hand, there is an optimal harvesting (EH) time duration, minimizes OP. This value depends transmission source Monte-Carlo simulations conducted validate derived mathematical expressions.
