In this paper, a general four-parameter end-to-end signal-to-noise with distortion ratio (SNDR) model for single-branch dual-hop amplify-and-forward (AF) relaying with/without the presence of transceiver hardware impairments is proposed. This model encompasses standard as well as non-standard AF relay configurations for both ideal and non-ideal transceiver hardware cases. A unified framework to evaluate the performance of single-branch dual-hop AF relaying is then formulated. This is accomplished by deriving new closed-form expressions for some statistics of some functions of two independent Gamma random variables. Based on these closed-form expressions, an exact analytical expression for the outage probability (OP) and an upper bound for the ergodic capacity are derived. Monte Carlo simulations’ results are provided to verify the accuracy of the analytical results.
