Line equalizer for digital signals. |
摘要 |
<p>A digital adaptive equalizer equalizes received signals through digital filtering operations by changing filtering coefficients. It comprises a coefficient calculating unit (102) for calculating the filtering coefficients through functionally transforming one kind of parameters, such as distance, by using it as an input to a function corresponding to the respective ones of said filtering coefficients and a filtering operation executing unit (104) for executing digital filtering operations based on the respective one of the filtering coefficients. A variable lag filter (202) for adjusting the phase delay of received received signals is provided. A coefficient converting unit (203) calculates a part or all of tap coefficients of the filter by converting at least one piece of timing control information. <IMAGE> <IMAGE></p> |
