Underwater acoustic communication is an active area of research due to its applicability in many industries. In comparison to other forms of underwater communication, acoustics provide a useful combination of versatility, range, and high data rates. However, the underwater acoustic channel presents several challenges to communication. To combat some of these issues, the use of hydrophone arrays with transmitting and receiving elements has been shown to be effective. By leveraging the spatial diversity provided by an array of hydrophones, some of the channel effects can be mitigated, improving the potential performance of both transmitters and receivers. Our team has developed software to transmit and receive signals between two Software Defined Radios with a uniform linear array for transmission and reception.
