Determining the Suitability of FPGAs for a Low-cost, Low-power Underwater Acoustic Modem

چکیده
T Few dense underwater acoustic sensor networks (UWSN) currently exist because existing commercial acoustic modems are too expensive and power consuming. In order to enable the proliferation of UWSN, a new low-cost, low-power acoustic modem must be designed. This paper investigates the appropriate computational platform and presents the design of a complete FPGA implementation of a Frequency Shift Keying (FSK) underwater acoustic modem for the first time as our best acknowledge, and also includes the real pool and lake test results to verify design performance. In the end, we compare its cost and power consumption to other research underwater modem designs implemented on different hardware platforms.

Design and Implementation of an Omni-Directional Underwater Acoustic Micro-Modem Based on a Low-Power Micro-Controller Unit
For decades, underwater acoustic communication has been restricted to the point-to-point long distance applications such as deep sea probes and offshore oil fields. For this reason, previous acoustic modems were typically characterized by high data rates and long working ranges at the expense of large size and high power consumption. Recently, as the need for underwater wireless sensor networks...
