The invention relates to a method for a filter bank based signal processing system. In order to enable a signal processing with a low complexity and at the same time a good performance, a method is proposed which comprises in a first step performing a filter- bank based analysis for converting a complex higher-rate channel signal into oversampled lower-rate sub-channel signals, each sub-channel corresponding to a different frequency range. In a second step, the proposed method comprises processing the oversampled lower-rate sub- channel signals with a polynomial model of a system frequency response within the frequency range of the respective sub-channel. The invention relates equally to a unit and a system comprising means for realizing the proposed method.
