Abstract
In order to determine the optimal sampling point for a series of spread-coded data, received by a radio, a correlation data series is used that is produced by convoluting the channel impulse response of the transmission channel with the spread data series, known at the receiving end. The channel impulse response is determined using a channel estimator according to a training sequence. An early-late correlator correlates the correlation data series with the received data in order to generate a correction signal for the optimal sampling point.
