Abstract
A method and system of demodulating a received transmission is disclosed. The method comprises disassembling a symbol sequence into a before sequence, a current symbol, and an after sequence. The method also comprises calculating correlations for all possible before sequences and determining the largest correlations for the before sequences, and placing into a first group. Further, the method comprises calculating correlations for all possible after sequences and determining the largest correlations for the after sequences, and placing into a second group. Further still, the method comprises piecing together the sequences of the first group, the second group, and the current symbol, to form a third group. Yet further still, the method comprises calculating the correlations for the third group and determining the largest correlation of the third group.
