Implementation of Adaptive Filter Algorithm for Underwater Acoustic System

This paper describes development of adaptive filter algorithm for an UnderWater Acoustic Telemetry (UWAT) system for communication between the off - shore Underwater Device (UD) and on-shore communication system. In this system, FSK modulation and de-modulation techniques are used with centre frequency of 38 KHz with baud rate of 300Hz. Adaptive filter algorithm has been developed to compensate the distortion introduced due to multipath in under water communication.
