Description
Summary:In this paper, we propose a mixed dual-hop communication system consisting of terahertz/underwater wireless optical communication (THz-UWOC) links with hardware impairments. In particular, considering the heterodyne detection, we assume that the THz link obeys <inline-formula> <tex-math notation="LaTeX">$\alpha $ </tex-math></inline-formula>-<inline-formula> <tex-math notation="LaTeX">$\mu $ </tex-math></inline-formula> fading with pointing errors (PEs), while the UWOC channel experiences a mixture exponential-generalized gamma (EGG) fading with pointing errors. Assuming a fixed gain amplify-and-forward (AF) and decode-and-forward (DF) relaying protocols, the closed-form expressions of the outage probability, in terms of the bivariate Fox&#x2019;s H-function is derived. Finally, the Monte Carlo simulation verifies the analytical results, which demonstrates the effect of turbulence conditions, different fading, and pointing errors on the system performance.
