Using a frequency weighted error function to improve performance of adaptive filters

The authors presents an enhancement to the error measurement function of an adaptive process. This enhancement enables the error to be weighted differently in different parts of the spectrum. The result is used to produce an adaptive process that adapts better to a given system, over a selective range of frequencies. The equations for an adaptive FIR system are derived. Finally some simulation results using the suggested method with an LMS process, are given.<
