Sign Decision Dual-Mode Blind Equalization Algorithm Based on Orthogonal Wavelet Transform

摘要：

Aiming at the big residue error and the slow convergence rate of the Constant Modulus blind equalization Aigorithm(CMA), a new orthogonal Wavelet Transform based Sign Decision Dual-Mode blind equalization Algorithm(WTSDDMA) is proposed. The proposed algorithm unit the WTCMA and the WT-MMA and switch between WT-CMA and WT-MMA by the method of sign decision. Simulation tests with underwater acoustic channel have indicated that the convergence rate of WT-SDDMA is superior to the CMA、 WT-CMA and WT-MMA, the residue MSE of that is smaller compared with the CMA and WT-CMA. Furthermore, the adaptive equalization principle block diagram based on orthogonal Wavelet is given.
