Abstract
A device for allocating a number of taps of a designated finite impulse response filter is disclosed. The device comprises a plurality of designated finite impulse response filters having fixed number of taps, a plurality of allocation finite impulse response filters having fixed number of taps, a control unit and an estimate unit. Depending on intensities of responses to interferences, at least one of the allocation FIR filters may be coupled in series to any one of the designated finite impulse response filters, thereby to provide a signal having excellent quality.
