Coupled Research in Ocean Acoustics and Signal Processing for the Next Generation of Underwater Acoustic Communication Systems
Abstract
Technical work this period focused on Research Task 1 from Section 2.2 of the Technical Approach and Justification. Specifically, work began on developing a methodology within the framework of asymptotic random matrix theory (RMT) to explicitly model the time variability of acoustic channels and using this to predict underwater acoustic communications systems performance. Prior methods have accommodated time variability by assuming that the channel is time invariant over an appropriately short interval of time. By explicitly modeling the time variability within the RMT framework it is hoped that the resulting analysis will more accurately predict the trade-offs associated with the rate of channel fluctuations, the number and configuration of hydrophone array elements, the size of filters in subsequent equalizers, and the structure of the equalizer adaptation algorithms. During this time period, the Principle Investigator also wrote, revised, and/or submitted papers based upon past work and delivered one talk at and helped prepare another one for the UComms 2014 conference.
