Bit Error Rate, Power And Area Analysis Of Multiple Fpga Implementations Of Underwater Fsk, Ying Li, Bridget Benson, Ryan Kastner, Xing Zhang

Electrical Engineering

There has been an increasing interest in creating short-range, low data-rate underwater wireless sensor networks for scientific marine exploration and monitoring. However, the lack of an inexpensive, low-power, underwater acoustic modem is preventing the proliferation of these sensor networks. Thus, we are building an underwater acoustic modem that considers cost and power at every level, from the analog electronics, to the modulation scheme, to the hardware platform. In this paper, we use reconfigurable devices to explore the design space of our modulation scheme – Frequency Shift Keying (FSK) – to select an implementation that provides the lowest power and area …
