ICASSP - Complex non-orthogonal joint diagonalization with successive givens and hyperbolic Rotations
2012 IEEE International Conference on Acoustics Speech and Signal Processing (ICASSP), 2012Co-Authors: Xiao-feng Gong, Ke Wang, Qiu-hua LinAbstract:Complex blind source separation (BSS) received growing interests in many practical applications in the past decades, and non-orthogonal joint diagonalization (JD) of a set of complex matrices plays an instrumental role in solving these problems. In this paper, we propose a new complex non-orthogonal JD algorithm. This algorithm successively finds the optimal Givens and hyperbolic Rotation matrices that constitute the Elementary Rotation Matrix in each iteration in an alternating manner. It does not require the target matrices to be Hermitian, and thus could be well adapted to BSS problems that involve fourth-order cumulant slices or time-lagged covariance matrices. Simulations are provided to compare the proposed algorithm with other JD algorithms.

Construction of Compactly Supported Orthonormal Multi-Wavelet
Journal of Shantou University, 2010Co-Authors: Zheng Li-eAbstract:In this paper,a method is given to generate a new multi-wavelet with the corresponding properties from a compactly supported symmetric orthonormal multi-wavelet by choosing Elementary Rotation Matrix and Elementary reflection Matrix.A class of balanced wavelets can also be constructed using this method.At last,the DGHM compactly supported symmetric orthogonal multi-wavelet is given in the method as an example.
