Abstract
A receiver includes an adaptive equalizer, a power detecting unit and an adjusting unit. The adaptive equalizer is for receiving a signal and generating an equalized signal. The power detecting unit, coupled to the adaptive equalizer, is for detecting the strength of the equalized signal during a first period to generate a first strength signal, and detecting the strength of the equalized signal during a second period to generate a second strength signal. The adjusting unit, coupled to the power detecting unit and the adaptive equalizer, is for adjusting the compensation strength for the adaptive equalizer according to the first and second strength signals.
Claims20
A receiver, comprising:
- an adaptive equalizer, for receiving an input signal and generating an equalized signal;
- a power detecting unit, coupled to the adaptive equalizer, for detecting the equalized signal during a first period to obtain a first strength signal, and detecting the equalized signal during a second period to obtain a second strength signal;
- and
- an adjusting unit, coupled to the power detecting unit and the adaptive equalizer, for adjusting a compensation strength for the adaptive equalizer according to the first strength signal and second strength signal.
A method for adjusting a compensation strength for an adaptive equalizer of a receiver, comprising:
- equalizing an input signal with the adaptive equalizer to generate an equalized signal;
- detecting the equalized signal during a first period to obtain a first strength signal, and detecting the equalized signal during a second period to obtain a second strength signal;
- and
- adjusting the compensation strength for the adaptive equalizer according to the first strength signal and the second strength signal.
