ABSTRACT:
A method for synchronizing to a CDMA-signal that contains a pilot sequence, overlaid with data sequences, comprises the following process steps: correlating the total signal consisting of the transmitted pilot sequence and transmitted data sequences with a reference pilot sequence; subtracting the correlation result time-delayed by one or more symbol durations of the pilot sequence from the current correlation result in order to suppress the pilot sequence and subsequent incoherent averaging, and determining the minimum.
