Adaptive equalizer and method thereof

An adaptive equalizing method applied to an adaptive equalizer, which comprises:

• an adaptive equalizing unit, for adaptively equalizing an inputted signal to output the equalized signal;
• a coefficient updating unit, for updating a coefficient of a filter of the adaptive equalizing unit;
• the adaptive equalizing method comprising:
• a phase detecting step, for detecting a down sampling phase of the inputted signal or a down sampling phase of the equalized signal;
• a determining step, for determining whether the phase detected by the phase detecting step is within a predetermined range;
• and
• a controlling step, for controlling update of the coefficient of the filters of the adaptive equalizing unit in accordance with the determination result of the determining step.

An adaptive equalizing method applied to an adaptive equalizer, which comprises:

• a plurality of adaptive equalizing units, for adaptively equalizing respective inputted signals to output the equalized signals;
• a plurality of coefficient updating units, corresponding to the plurality of adaptive equalizing units, for updating coefficients of filters of the corresponding adaptive equalizing units;
• the adaptive equalizing method comprising:
• detecting a down sampling phase of the inputted signal or a down sampling phase of the equalized signal of one adaptive equalizing unit;
• and
• controlling to update the coefficients of the filters of the one or more adaptive equalizing units when the phase detected by the detecting is within a predetermined range.
