Abstract (en)
[origin: WO0033102A1] A receiver for direct sequence code division multiple access (DS-CDMA) signals particularly for GPS signals includes a plurality of correlators. The correlators include a multiple delay and summing circuit (29) which produces mutually offset versions of the received signal which are summed and then correlated with the spreading code. Alternatively an element (39) takes the output of the code NCO (26) and produces from it multiple offset versions of the spreading code summed together which are correlated with the received signal. Correlation will be achieved if any one of the multiple offset received signals correlates with the locally generated spreading code or if any one of the offset spreading codes correlates with the received signal.
