Abstract
A method () and apparatus () provide channel estimation with extended bandwidth filters. Antenna () receives a signal such as a pilot signal and detects a bandwidth associated with the pilot signal in a detector (). One of a plurality of filters (, and) including extended bandwidth filters () and a default filter () can be selected by a selector (). If the detector detects activity associated with a wider bandwidth, the filter associated with the wider bandwidth is selected over the presently selected filter. If no activity is detected, the default filter is selected.
