<p>A method of, and receiver for, recovering data bits from a spread spectrum signal, in which a digitally sampled chip sequence is derived from a received spread spectrum signal, a matched filter (34) filters the digitally sampled chip sequence in a matched filter, a circuit (36) obtains a running average of the output from the matched filter over successive bit periods, which of the matched filter output samples corresponds to the maximum value in the running average and determines the sign of the sample in a stage of the matched filter synchronised with maximum value and assigns a data bit value in accordance with the sign.</p> |
