Performance of SWIPT-Enabled FD TWR Network With Hardware Impairments and Imperfect CSI

Cooperative communication with energy harvesting capability increases network coverage and provides a green sustainable solution for future wireless technologies. In this article, we analyze the performance of two-way relay network, where bidirectional information exchange between two nodes takes place via simultaneous power transfer-enabled node, operating in full-duplex (FD) mode over generalized Nakagami- $m$ fading channels. Different nonlinear amplifier (NLPA) models, such as solid-state amplifier, traveling wave tube soft envelope limiter, are considered at node. The effect practical constraints, imperfect channel state (CSI) transceiver hardware impairments (HIs), is considered. Further, consider impact residual self-interference (RSI) due to successive interference cancellation FD mode. For analysis, closed-form expressions outage probability (OP), asymptotic OP, system throughput, efficiency, ergodic capacity, capacity derived. diversity order evaluated. CSI, NLPA, HIs, RSI, other parameters highlighted on performance. half-duplex also compared. Monte Carlo simulations confirm accuracy derived expressions.
