Robust digital communication in time-varying noise

摘要: A digital communication system is developed, using moving average matched filter (MAMF) detectors, for environments where the noise unknown a priori and may change constantly significantly. in which basis vectors representing signal subspace are transmitted rather than fixed vector described. At receiver basis-vectors linearly combined so that output signal-to-noise ratio (OSNR) of MAMF maximized. This linear combination represents an adaptation to changes environment. combining approaches simulated shown potentially outperform either alone arbitrary distribution narrowband center frequencies. >
