Title:
SIGNAL FILTERING METHOD AND APPARATUS, AND DATA PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/102831
Kind Code:
A1
Abstract:
Provided by the present application are a signal filtering method and apparatus, and a data processing device. The method comprises: acquiring a signal to be processed; and filtering the signal by using a preset filter function that has a differential constraint so as to obtain a filtered signal, wherein the difference constraint is to superimpose a differential value of a preset multiple of the preset filter function on a filtering result of the preset filter function. The solution provided by the present application starts from the perspective of studying the difference between a real smooth signal and a signal that contains noise. By means of filtering the signal to be processed by using a preset filter function that has a differential constraint, the signal difference may be further reduced in the filtering result of the preset filter function, so that the smoothness of the filtering result may further be improved without affecting the phase deviation.
