Yecai Guo, Liu Zhenxing · Acta Armamentarii · 2010
In order to overcome the slow convergence rates of constant modulus algorithm(CMA),a balance orthogonal multiwavelet transform based constant modulus blind equalization algorithm(MWTCMA) was proposed.Balance orthogonal a multiwavelet was introduced into the algorithm for compensating the absence of prefiltering to multiwavelet in actual application,and the common form of orthogonal multiwavelet transform matrices was deduced.The simulated results by MWTCMA in underwater acoustic channels show that the proposed MWTCMA outperforms CMA and WTCMA in convergence rate and mean square error.
