Minimum covariance spectrum (MCS) estimation method is not robust in alpha stable distribution because of no finite covariance. A pseudo-power spectrum estimation method based on fractional low-order covariance (FLOC) matrix is proposed in this paper to improve MCS estimation method. The pseudo-power of a frequency point can be obtained by using FLOC matrix, and its pseudo-power spectrum (PPS) can...Show More
A fast algorithm of logarithm-form fractional lower-order spectrums is proposed in this paper in order to be facilitative for practice application that traditional fractional lower-order spectrums need to identify characteristic exponent alpha and improve its calculating speed for alpha stable distribution signal or noise. The algorithm is not depended on a prior knowledge of characteristic expone...Show More
A white alpha stable distribution noise (WASDN) and its pseudo-power spectrum (PPS) is exactly proposed in this paper to analyze better frequency domain characteristic of alpha stable distribution noise. By a PPS estimate method based on fast Fourier transform (FFT), we can conclude that the method can have finite variance only there is four-order moments to transformed sequence and the estimate v...Show More
A decision-feedback equalizer based on zeros-order statistics is proposed in this paper to improve the performance and convenience of the method based on fraction low-order statistics which needs to identify characteristic exponent alpha. The new method uses an iterative factor based on zeros-order statistics to renew weight coefficients of adaptive equalizing filter. The coefficient factor can re...Show More
The whitening problem of colored noise had been resolved for Gaussian white noise through linear system, but other inputs through other systems had not been resolved which includes non-Gaussian white noise through linear or nonlinear system. This paper briefly proposed an improved iteratively reweighted least P norm (IIRLP) algorithm for whitening in alpha-stable environments. And the parameters i...Show More
Generalized Fractional Lower-order Covariance Spectrum (GFLO-CVS), Cyclic Spectrum (GFLO-CYS) and Higher-order Spectrum (GFLO-HOS) are proposed. After a nonlinear transform is used in alpha stable distribution process for getting finite second-order or high-order moment, consequently, Fourier transform of transformed stochastic process can be employed to analyze characteristic in frequency domain....Show More
Alpha stable distribution is better for modeling impulsive noises than Gaussian distribution in signal processing. We proposed a new adaptive recursive least p-norm Kalman filtering algorithm and a new robust CDMA multiuser detection method based on least p-norm Kalman filtering. The simulation experiments show that the proposed new algorithm is more robust than the conventional Kalman filteringShow More
