1. A method for decoding a code division multiplex signal using one of a plurality of individual codes available for decoding, comprising:
combining at least some of the individual codes to generate combination codes;
comparing each of the combination codes with the received code division multiplex signal;
determining a most similar combination code to the code division multiplex signal, from among the combination codes;
determining a most similar individual code to the code division multiplex signal, from among the individual codes forming the most similar combination code; and
decoding the received code division multiplex signal using the most similar individual code.
