High Data Rate Acoustic Massive MIMO for Underwater Communication

The demand for high definition real time applications for explorations and surveillance of underwater and marine environments is unprecedented, and also in defense applications and autonomous underwater vehicles (AUVs). These applications require high data rate with improved throughput and low error performance in underwater acoustic communications. In this paper, Massive Multi input multi output (MIMO) technique is proposed with Signal-to-leakage plus noise ratio maximization (SLNR-Max) based precoding method to amplify and achieve the desired performance enhancement. Here, it has been established that by increasing the number of transducers/hydrophones at the buoy station (BS), there is significant improvement in error performance and capacity. Proposed method for underwater communication channel can yield greater performance with high spectral efficiency and low error probability
