FPGA based Underwater System for Ultrasound Communication

Pooja Sabale | S.T. Khot

Abstract: This paper presents the design consideration, implementation details and initial experimental results of our modem. This paper also discusses the various modulation technique like ASK. This design uses commercial ultrasonic transducer of 200kHz bandwidth. Massage from transmitter can be displayed in visual format as well as it can be analyzed using different simulation tools at base station. Under water modem consists of three component i) An underwater ultrasound transducer ii) An analog transceiver (matching pre-amplifier and amplifier), iii) A digital platform for control and signal processing. In this paper comparison of results of communication with ASK modulation technique, microcontroller & FPGA.
