Unified Performance Assessment of Optical Wireless Communication Over Multi-Layer Underwater Channels

Blog Article

In this paper, we model the multi-layer vertical underwater link as a cascaded channel and unify the performance analysis for the underwater optical communication (UWOC) system using generalized Gamma (GG), exponential GG (EGG), exponentiated Weibull (EW), and Gamma-Gamma ($Gamma Gamma$) oceanic turbulence models.We derive unified analytical expressions for probability density function (PDF) and cumulative distribution function (CDF) for the signal-to-noise ratios (SNR) considering independent and non-identical (i.ni.d.) turbulent models and zero bore-sight model for pointing errors.

We develop performance metrics of the considered UWOC system using outage probability, average bit error rate (BER), and ergodic capacity Revisiting residential self-selection issues: A life-oriented approach with asymptotic expressions for outage probability and average BER.We develop the diversity order of the proposed system to provide a better insight into the system performance at a high SNR.We also integrate a terrestrial OWC (TOWC) subjected to the combined effect of generalized Malága atmospheric turbulence, fog-induced random path gain, and pointing errors to communicate with the UWOC link using the fixed-gain amplify-and-forward (AF) Risk of Central Serous Chorioretinopathy in Male Androgen Abusers relaying.We analyze the performance of the mixed TWOC and multi-layer UWOC system by deriving PDF, CDF, outage probability, and average BER using the bivariate Fox H-function.We use Monte-Carlo simulation results to validate our exact and asymptotic expressions and demonstrate the performance of the considered underwater UWOC system using measurement-based parametric data available for turbulent oceanic channels.
