Abstract
A first searcher searches a first channel (e.g., a broadcast channel), a second searcher searches a second channel (e.g., a traffic channel), and the second searcher uses information from the first searcher to search the second channel. In one aspect of the invention, the first searcher generates a delay profile for the first channel. A second searcher uses the delay profile to generate a set of taps for the second channel. In another aspect of the invention, the first searcher is configured to find a maximum correlation value (or a set of maximum correlation values). The second searcher shifts a search finger by an amount equal to the delay corresponding to the maximum correlation value(s). The second searcher can also shift a code corresponding to the second signal by an amount equal to the sum of the delay corresponding to the maximum correlation value(s) and a predetermined value.
