Modeling and Interpretation of Beamforming Gain and Diversity Gain for Underwater Acoustic Communications

摘要

Output signal-to-noise ratios for a multichannel decision feedback equalizer were measured from experimental BPSK data as a function of the receiver spacing, number of receivers used, and array aperture and reported in a paper in OCEANS 2005 by the author. This paper discusses the theory and reports numerical modeling results to compare with the data.
