Abstract

Recent studies show that a vector transducer which measures signal in acoustic particle velocity channels can serve as a compact multichannel communication receiver. In this paper, data transmission via underwater particle velocity channels using a vector transducer is investigated. System and channel equations are derived, and a method for signal modulation in particle velocity channels is proposed. The signal is transmitted with opposite polarities, which makes the received signal the convolution of the transmitted signal and a particle velocity channel response. System performance analysis demonstrates the feasibility and advantages of data transmission using a vector transducer.
