摘要：

Underwater acoustic channel (UACh) requires robust techniques to get high speed data transmission for reliable communication. This paper presents the adaptive transmission technique in conjunction with the maximal ratio combining (MRC) diversity technique to adapt the UACh fluctuation based on a statistical channel model. Simulation analysis shows that we can optimize the data rate allowing the transmit power to vary with SNR, subject to an average power constraint, and also shows that data rate can be increased under adaptive technique in conjunction with two branch diversity. Under the optimum data rate, the Matlab simulink of UACh QPSK communication system gives a benchmark for the future real experiment in the ocean.
