A new compact multichannel receiver for underwater wireless communication networks

In this letter it is shown that by taking advantage of the particle velocity, in addition to the pressure, multichannel reception can be accomplished in underwater acoustic wireless channels. Theoretical formulation and Monte Carlo simulations are provided for a vector sensor equalizer that measures the pressure and the velocity at a single point in space. These results demonstrate the usefulness of small-size vector sensors as multichannel equalizers for underwater acoustic wireless systems and sensor networks.
