Coupled Research in Ocean Acoustics and Signal Processing for the Next Generation of Underwater Acoustic Communication Systems

Abstract

Technical work this period has spanned four areas. The first was continuation of work 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. The background can be found in Progress Reports #3 and #4 for the prior two reporting periods. In this reporting period, a simplification of a particular cross-correlation matrix was developed which greatly simplifies the expressions. Work continues on both the full complexity and simplified expressions to determine if the simplified expression still accurately models the problem. This work falls under Research Task 1 from Section 2.2 of the Technical Approach and Justification.
