Abstract
In one embodiment, a method includes generating a set of sequences of chip values and calculating a correlation between a demodulated signal and each one of two or more of the sequences. Each of the correlations has an absolute value, and one of the correlations has a highest absolute value. The method includes selecting the one of the sequences with the correlation having the highest absolute value; identifying a sequence index corresponding to the selected one of the sequences; and, for each of one or more data symbols in the demodulated signal, determining a value of the data symbol based on the sequence index corresponding to the selected one of the sequences.
