Title:
SIGNAL PROCESSING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2016/050049
Kind Code:
A1
Abstract:
Disclosed are a signal processing method and apparatus. The method of the present invention comprises: filtering first input signals according to at least two groups of adaptive filters, so as to obtain filtered first input signals; acquiring initial signals of each group of adaptive filters according to second input signals and the filtered first input signals; and mixing the initial signals of each group of adaptive filters, so as to obtain final signals. By means of the present invention, the problem that the signal processing performance is degraded due to misjudgment of a hard decision mode can be avoided.
