A problem to enhance multirate adaptive filtering in equalization problem of nonstationary signals is considered. It is demonstrated that two special transformations on filter taps of adaptive cores in multirate adaptive structure lead to high-level precision and performance and allows eliminating of additional delay caused by analysis/synthesis subsystem at the same time. The paper is supplied by experimental results for speech signals which help to estimate the efficiency of proposed multirate adaptive filtering structure. The aim of this scientific research is to increase the efficiency of multirate adaptive filtering in equalization problem of non-stationary signals.

Key words: multirate signal processing, adaptive filter, filter taps transformation.
