Underwater Wireless Communication Systems.

1. Investigating the performance of time reversal underwater acoustic communication considering underwater channel characteristics like absorption, spreading, scattering, sound speed and multipath with the help of specialized beam tracing software BELLHOP.
2. Statistical analysis of deep-sea underwater acoustic channel for the Indian Ocean region.
3. Performance study of a three-node cooperative underwater wireless optical communication (UWOC) system considering the combined effect of attenuations and turbulence while channel modelling.
4. Performance study of multi-relay horizontal and vertical cooperative UWOC system.
