Abstract
A method and apparatus for dynamically varying the response of a digital filter in a pilot signal detection circuit in response to the number of pilots that are scheduled to be searched. The apparatus comprises a searcher subsystem for generating a pilot energy sample. The pilot energy sample is then digitally filtered in a filter whose coefficients are determined in response to the number of pilots that are scheduled to be searched. A control processor determines the number of pilot signals to be searched, and calculates a filter length in response to the number of pilot signals to be searched. Furthermore, the control processor filters the pilot energy sample according to filter coefficients which are based on the calculated filter length.
