A novel adaptative frequency-shift filter
Na Xiao, Yang Cui-e · Applied science and technology · 2004
This paper introduces the frequency-shift filter which is based on the spectrum correlation theory. Based on this model, two adaptive FRESH filters are brought forward, one of which adopts the LMS algorithm and the other adopts the CMA algorithm. The simulation results demonstrate that CMA-FRESH filter which doesn't require training sequence has similar performance with conventional LMS-FRESH filter and is a kind of practical FRESH filter.
