Closed Form Expressions for Underwater‐RF System Over Decode‐Forward Relaying

Journal of Sensors, Volume 2025, Issue 1, 2025.
In the development of advanced communication systems for the underwater‐radio frequency (RF), use of relay has been found highly significant. Due to multipath fading and shadowing, performance of any wireless communication is severely degraded. Using relay‐based communication system deployed in the severe fading environment, we can achieve significant ...
