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

Abstract

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

Outage and ergodic capacity analysis of a full‐duplex energy‐harvesting cooperative non‐orthogonal multiple access network

“…As per our knowledge, few of them related to this work are referenced in from previous studies. [14][15][16][17][18][19][20] Zhang and Ge have studied the outage performance and achievable data rate for HD-EH-CR-NOMA network, 14 while Kiran and Swaminathan 15 have analyzed the outage performance with ergodic capacity in partial relay selection scheme. Ding et al 16 have investigated the impact of power allocation on users with fixed power and cognitive inspired power, while Li et al 17 have analyzed the outage performance in a cognitive radio system by formulating two optimization problems to achieve maximal secondary user throughput.…”

“…Recently, several works are done related to single‐source half‐duplex (SS HD), FD energy‐harvesting cognitive radio NOMA (FD‐EH‐CR‐NOMA) network. As per our knowledge, few of them related to this work are referenced in from previous studies 14–20 . Zhang and Ge have studied the outage performance and achievable data rate for HD‐EH‐CR‐NOMA network, 14 while Kiran and Swaminathan 15 have analyzed the outage performance with ergodic capacity in partial relay selection scheme.…”

“…Liu et al 10 studied the outage and system throughput performance with PSR protocol where near user acts as a relay to help far user. Li et al 18 studied the outage and ergodic rate performance of HD‐EH‐CR‐NOMA considering the effects of residual hardware impairments (RHIs), imperfect channel state information (ipCSI), and imperfect successive interference cancellation (ipSIC), while outage and ergodic performance was studies by the Kumar et al 19 using an FD‐EH‐CR‐NOMA network over a generalized Nakagami‐ fading channel under the effects of RHIs, ipCSI, and RSI. Li et al 20 studied the outage and throughput considering the effect of ipCSI and RHIs over Weibull faded channel, while Tang et al 21 have investigated the joint power allocation and splitting control in HD‐EH‐CR‐NOMA network.…”

On Performance of a SWIPT Enabled FD CRN With HIs and Imperfect SIC Over α–μ Fading Channel

“…For 5G and beyond network design, EE is an important performance metric that supports high-speed data rates while minimizing power consumption for a longer battery life. For the considered network, the energy efficiency can be defined as the total transferred data to the total consumed power [48]- [50]. The total transferred data is referred to as throughput while the total consumed power can be evaluated as the power consumed at SU c during EH Phase and IT Phase.…”

Performance Analysis of NOMA System with QoS-Guarantee Scheme

“…Further, in practical communication systems, various radio frequency (RF) transceiver components suffer from hardware impairments (HI). The HI is mainly caused due to frequency and phase offsets, non-linear power amplifiers, and in-phase and quadrature (I/Q) imbalance resulting in significant performance deterioration of the system [22,23]. Although sophisticated and advanced signal processing techniques can be used to minimize the effect of performance degradation because of HI, however, the HI cannot be removed entirely.…”
