1. A method of determining a modulation type of a received signal, the method comprising:

  • beginning demodulation of the received signal using components associated with each potential type of modulation;

    providing an identification value to a voting block for each potential type of modulation based on the received signal; and

    using a technique in the voting block to determine the modulation type, wherein the technique is based at least on the identification values and including determining a strength of the received signal,wherein if the strength of the received signal is equal to or less than a predetermined threshold value, thereby characterizing the received signal as weak, then the identification value includes a normalized correlation value based on characteristics of the modulation type.
