    摘要: A method (200) for detecting a periodic signal (141) in a noisy signal (101) is provided. The method can include applying (210) correntropy to the noisy signal to generate a non-linear mapping, and applying (220) a sub-space projection to the non-linear mapping to produce principal components. A correntropy kernel can be applied to the noisy signal to generate a Gram matrix that is used in a Temporal Principal Component Analysis (TPCA). The correntropy kernel projects nonlinearly the input data to a reproducing kernel Hilbert Space (RKHS) preserving the input time structure and attenuating impulsive noise. The correntropy kernel is data dependent, and the RKHS correlation matrix has the same dimension as the input data correlation matrix. A principal component having a majority of signal energy can be chosen (230) to detect the periodic signal.

    摘要: A signal processing method is provided. The method includes receiving a signal input, and filtering the signal input using a nonlinear correntropy filter. The method additionally includes generating an output based upon the filtering of the signal input. The nonlinear correntropy filter can be configured as a nonlinear Wiener filter. Alternatively, the nonlinear correntropy filter can be configured as a correntropy least mean square (LMS) filter, or a correntropy Newton/LMS filter.
