For greatly overcoming the disadvantages of low convergence rate and local minima of constant modulus algorithm(CMA), a support vector machine blind equalization algorithm based on orthogonal wavelet transformation(WT-SVM) was proposed. The proposed WT-SVM algorithm employs the support vector machine for overcoming the local minima in convergence process and uses orthogonal wavelet transform to reduce...
Aiming at the slow convergence rate and the high mean square error of constant modulus algorithm(CMA), a new orthogonal wavelet transform based sign decision dual-mode blind equalization algorithm(WT-SDDA) is proposed. In the proposed algorithm, orthogonal wavelet transform based constant modulus algorithm (WT-CMA) is integrated with orthogonal wavelet transform based stop-and-go changeable modulus...
In order to overcome the slow convergence rate and large mean square error (MSE) of constant modulus algorithm (CMA), an equalizer and its output are expressed by a family of orthogonal wavelet packet functions. Then, a super-exponential iterative blind equalization algorithm based on orthogonal wavelet packet transform (WPT-SEI) is proposed, via the analyzing of the futures of wavelet packet transform...
