A communication system receiver sorts through potential Walsh indexes and determines survivors for use in subsequent processing. The sort process is implemented in parallel with the subsequent processing so that large amounts of memory to implement a store/sort are eliminated. The communication system receiver implements the sorting operation in a small number of cycles, thereby conserving cycles which could be beneficially utilized for other tasks as required. The sorting operation also lends itself well to a practical implementation from a communication system receiver design perspective.

[ What I claim is:] [10.] An apparatus for sorting a plurality of Walsh indexes in a communication system receiver, the plurality of Walsh indexes present in a plurality of Walsh symbols, the apparatus comprising:means for determining the energy of each Walsh index present in one Walsh symbol of the plurality of Walsh symbols;means, coupled to said means for determining, for comparing the determined energy of each Walsh index with all other Walsh indexes present in the one Walsh symbol;means, coupled to said means for comparing, for sorting a predetermined number of Walsh indexes, in parallel with the energy determination, for use in subsequent energy determinations of other Walsh indexes present in other Walsh symbols to produce sorted Walsh indexes based on the comparison of the determined energy; andmeans for storing data related to the sorted Walsh indexes.
