New Spatial Diversity Equalizer applied to underwater acoustic channels
摘要
Abstract
Underwater acoustic communication is difficuIt because the fading muItipath channeIs have high-order QAM sig-naIs. A new SpatiaI Diversity EquaIizer( SDE)is proposed to overcome the inter-symboI interference( ISI)in underwater a-coustic channeI. The aIgorithm in the proposed SDE consists of constant moduIus aIgorithm( CMA)part and muIti-moduIus bIind equaIization aIgorithm part. The second part of the proposed SDE can use the different moduIus nature of the high-order QAM signaIs to improve the equaIization performance. Compared with the traditionaI SDE based on CMA,the proposed SDE can obtain the Iower steady-state mean square error and faster convergence rate. The performance of the proposed SDE is shown in underwater acoustic channeIs by computer simuIations.关键词
