Abstract
A digital adaptive equalizer equalizes received signals through digital filtering operations by changing filtering coefficients. It comprises a coefficient calculating unit for calculating the filtering coefficients by using one kind of parameters, such as distance, as an input to a function corresponding to the filtering coefficients and a filtering operation executing unit for executing digital filtering operations based on the filtering coefficients. A variable lag filter for adjusting the phase delay of received received signals is provided. A coefficient converting unit calculates a part or all of tap coefficients of the filter using at least one piece of timing control information.
