A New Compact Multichannel Receiver for
Underwater Wireless Communication Networks

Abstract--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.

A vector sensor is capable of measuring important non-scalar components of the acoustic field such
as the particle velocity, which cannot be obtained by a single scalar pressure sensor. In the past few
decades, extensive research has been conducted on the theory and design of vector sensors (see, for
example,  and ). They have been mainly used for underwater target localization and SONAR
