1. A method of performing signal detection, comprising:

  • generating a first sequence of first symbol delayed products for a sequence of symbols, each first symbol delayed product resulting from at least a first product operation based on first and second symbols of the sequence of symbols that are separated by a first symbol delay;

    generating a second sequence of second symbol delayed products for the sequence of symbols, each second symbol delayed product resulting from at least a second product operation based on first and third symbols of the sequence of symbols that are separated by a second symbol delay;

    performing correlation between the first sequence and first known values to obtain first correlation results;

    performing correlation between the second sequence and second known values to obtain second correlation results; and

    detecting for presence of a signal based on the first and second correlation results.
