Research on Acoustic Three-User Communication Based on Single Vector Sensor

The vector sensor can be competent for measuring the information of pressure and velocity synchronously and independently. Acoustic multi user communication system based on single vector sensor, which can be used to separate several source from each other by calculating the inverse channel matrix, can be equivalent to MIMO system. Theoretical calculation and simulation have shown that the algorithm could be used to actualize the multi user communication system, and the separated source signal could be expect to acquire a certain amount of SNR gain. For the formation of underwater communication network, the research is of great significance and potential of engineering application.
