Abstract
A method and a device of sustainably updating a coefficient vector of a finite impulse response FIRfilter. The method includes obtaining () a time-varying regularization factor used for iteratively updating the coefficient vector of the FIR filter in a case that the coefficient vector of the FIR filter is used for processing a preset signal; updating () the coefficient vector of the FIR filter according to the time-varying regularization factor.
