Patent ID: 8265127

Claim:
A system comprising: one or more circuits configured to: receive a signal, the signal created in part based on a first set of sequences of chip values, each chip value of the first set of sequences of chip values having a first range of values; calculate for each of two or more of sequences of a second set of sequences of chip values a correlation based on the signal, each of the correlations having an absolute value, one of the correlations having a highest absolute value, at least one chip value of the second set of sequences of chip values having a second range of values, the second range of values being larger than the first range of values; select the sequence of the second set of sequences associated with the correlation having the highest absolute value; identify a sequence index corresponding to the selected one of the sequences; for each of one or more data symbols in the signal, determine a value of the data symbol based on the sequence index corresponding to the selected one of the sequences.
