Abstract
An apparatus, such as a subscriber unit or a base station within a spread spectrum communication system, may add one or more additional “virtual” paths to a list of candidate paths when assigning demodulation elements. These “virtual” paths are added as candidate paths even though a corresponding peak was not necessarily detected within a received spread spectrum system. The list of paths may include a first path having a time offset approximately equal to a time offset for one of the demodulation elements, and the virtual path having a short time separation from the first path. The time separation between the paths may be, for example, less than 2 chips.
