Performance Investigation of OFDM-Based Serial Relay UWOC System over the Generalized Gamma Distribution

In this work, an orthogonal frequency division multiplexing (OFDM) serial relay underwater wireless optical communication (UWOC) system has been investigated over the combined generalized gamma distribution (GGD) oceanic fading channel under different modulation schemes, temperature gradients, water types and number of relays. Besides, RS codes are applied to enhance the performance of this studied system. The results reveal that the impact of RS codes becomes more apparent with the increasing temperature gradients.
