Title:
最小二乗法を用いて導出されるインパルス応答のエラーキャラクタリゼーション推定値を提供するための方法および装置
Document Type and Number:
Japanese Patent JP2004537941
Kind Code:
A
Abstract:
A filter adaptation unit suitable for producing a set of filter coefficients is provided including an error characterization unit for characterizing the error in a filter's impulse response. The error characterization unit generates a set of error characterization data elements associated to a newly generated set of filter coefficents. A selection unit then makes a selection between one of the newly generated set of filter coefficients and an existing set of filter coefficients at least in part on the basis of their respective sets of error characterization data elements. The selected set of filter coefficients is then released in a format suitable for use by an adaptive filter.
