ABSTRACT
Low size, weight, power and cost (SWaP-C), agile programmability and rapid run-time reconfigurability are desired features for the design of adaptive, underwater wireless communication modems for micro autonomous underwater vehicle (μAUV) swarms. In this demo, we present a first generation software and hardware design of a new class of low SWaP-C underwater modems that can accommodate wideband acoustic front-ends and achieve μs-level reconfigurability during run-time. We demonstrate run-time reconfiguration between two modulation schemes: Binary Frequency Shift Keying (FSK) and Fast Frequency Hopping FSK in a point-to-point underwater communications link in a small water tank and show communication data rates of up to 2000 bps and bandwidths of up to 75 kHz with the implementation of custom programmable logic. For visualizing run-time reconfiguration in real-time, we deploy a co-located modem for monitoring acoustic spectrum activity in the water tank.
