CONTINUOUS UPDATING METHOD AND DEVICE FOR FINITE IMPULSE RESPONSE FILTER COEFFICIENT VECTOR

摘要

Provided are a continuous updating method and device for a finite impulse response filter coefficient vector. A continuous self-adaptive updating method for a finite impulse response (FIR) filter coefficient vector comprises: acquiring a time-varying regularization factor for FIR filter coefficient vector iterative updating when a pre-set signal is processed by using an FIR filter coefficient vector (21); and according to the time-varying regularization factor, updating the FIR filter coefficient vector (22).
