Abstract

This work investigates the performance of a full-duplex amplify-and-forward (FD-AF) relaying taking into account the residual self-interference at the relay node. We consider the

α

μ

distribution as fading channel model at the two links which well describes the small scale fading in terahertz (THz) communications. Full-duplex relaying can potentially double the spectral efficiency achievable by half-duplex operation considering the detrimental effects of inevitable self-interference. We derive the closed-form expressions of rate outage probability and ergodic capacity whereas an exact expression of average symbol error probability of coherently detected M-ary phase shift keying (M-PSK) is derived using the univariate and bivariate Fox’s H-functions. The derived expressions are valid for arbitrary values of the

α

μ

fading parameters. Through simulations, it has been revealed that the performance of the system improves when the relay is closer to the source node as compared to destination node. Moreover, it has been observed that the fading parameters of the source-relay link dominates the system’s performance as compared to the parameters of relay–destination link. The analytical expressions are ascertained by simulations which are found to be in excellent agreement.
