1. A device for searching signal paths comprising:
- a first stage configured to sort a plurality of signal energies into one of a plurality of ordered candidate signal lists associated with one of a plurality of antennas based on the strength of the plurality of signal energies; and
a second stage configured to sort the plurality of ordered candidate signal lists into a signal path list that is ordered based on the strength of the plurality of signal energies in the plurality of ordered candidate signal lists.

Abstract
A reverse link searcher to determine a signal path from multiple signal paths is shown. A reverse link searcher orders signal energies based on the strength of the signal energies and creates candidate signal lists that are each associated with one antenna. Also, the reverse link searcher orders signal energies in a candidate signal lists and creates a path selection list based on the strength of the signal energies in the candidate signal lists. This technique allows comparison operations to be minimized to reduce the processing time for a signal path selection.
