Abstract
An apparatus and a method for performing channel equalization in a digital broadcasting receiver based on a ghost level is disclosed. The apparatus includes a filtering unit and an equalization amplitude control unit. The filtering unit filters a received broadcasting signal and outputs an equalization channel output signal. If a ghost is included in the received broadcasting signal, the equalization amplitude control unit controls an equalization coverage area of the received broadcasting signal by controlling a filtering coefficient of the filtering unit based on the level of ghost.
Claims10
A channel equalization apparatus in a digital receiver, the apparatus comprising:
- a filter filtering a received signal and outputting a channel equalization output signal;
- and
- an equalization amplitude control unit controlling an equalization coverage area of the received signal by controlling a filtering coefficient of the filter based on a level of a ghost, if the ghost is included in the received signal.
A channel equalization method in a digital receiver, the method comprising;
- detecting a ghost from a received signal;
- detecting a level of the ghost as a detected level of the ghost;
- and
- controlling an equalization coverage area of the received signal based on the detected level of the ghost and performing channel equalization for the received signal.
A channel equalization apparatus in a digital receiver, the apparatus comprising:
- means for filtering a received signal and outputting a channel equalization output signal;
- and
- means for controlling an equalization coverage area of the received signal by controlling a filtering coefficient of the means for filtering based on a level of a ghost, if the ghost is included in the received signal.
