Abstract
In this paper, we investigate the end-to-end average signal-to-noise ratio (SNR) of dual-hop amplify-and-forward wireless communication systems operating over independent but not necessarily identically distributed (i.n.i.d.) \(\eta {-}\mu \) fading channels. Specifically, we derive a novel exact closed-form expression for the generalized end-to-end average SNR for arbitrary fading parameters \(\eta \) and \(\mu \). Using the obtained closed-form expression for the generalized end-to-end average SNR, some important performance metrics such as the average end-to-end SNR, the amount of fading and the channel capacity can be easily obtained. The effect of the fading parameters and the power imbalance on the overall system performance is investigated. The analytical results are validated by means of Monte-Carlo simulations.
