High Frequency Acoustic Propagation in Littoral and Surf Zone Environment: The Analysis of Temporal Fluctuations and Development of Adaptive Signal Processing Algorithms.

摘要

There are three long term goals of this work. The first is to the characterize features of high frequency acoustic propagation in shallow water that are relevant to the performance and design of acoustic communications systems. The second is to develop closed form expressions for the performance of channel identification and acoustic communications algorithms as a function of environmental conditions. The final goal is to develop improved channel estimation and demodulation algorithms for phase coherent acoustic communications in this environment.
