Abstract:
1. A method for improving a search for a timing of at least one cell, the method comprising: detecting, at a mobile station, a plurality of signals, each from one of a plurality of cells, wherein one of the plurality of cells is identified by the mobile station as a strong cell and the remaining cells are identified by the mobile station as weak cells; applying a first matched filter to the signal from the strong cell to detect first parameters associated with the strong cell; applying a second matched filter to at least one signal from one or more of the weak cells, resulting in at least one second matched filter output; removing from the at least one second matched filter output interference associated with the signal from the strong cell to detect one or more second parameters, including a second timing position, a second frequency offset, and a second amplitude; and selecting, at the mobile station, the second timing position that yields a maximum signal magnitude to establish a timing of one of the weak cells.
