Affordable underwater acoustic communications
Communication is an enabling technology for underwater systems such as autonomous underwater vehicles (AUVs), sensor networks, and diver support equipment. These systems cannot use radio frequency (RF) links, because radio waves are heavily absorbed by water, and poor visibility rules out optical links. Only acoustic communication is suitable. The underwater acoustic channel is bandwidth-limited, slow, and degraded by multipath, Doppler, and noise, making underwater modems a demanding signal processing and embedded systems problem.Commercial underwater modems exist but are expensive and …
