The detection unit includes a correlation unit, which is connected to the sequence providing unit and formed to calculate correlation results by correlating the differentially demodulated signal with each derived sequence of the third group. The detection unit includes an evaluation unit, which is connected to the correlation unit and is formed to derive the values of the data symbols by evaluating the correlation results.

The inventive detection unit comprises the following units: a) a sequence supplying unit that is configured for supplying a third group of derived sequences. Said third group of derived sequences is provided with a derived sequence for each first PN sequence, which is assigned to said first PN sequence and can be derived therefrom by means of logical combinations but is not identical thereto while the derived sequences of the third group are different from each other only by cyclically shifting the chip values thereof; b) a correlation unit which is connected to the sequence supplying unit and is configured for calculating correlation results by correlating the differentially demodulated signal with each of the derived sequences of the third group; and c) an evaluation unit that is connected to the correlation unit and is configured for deriving the values of the data symbols by evaluating the correlation results. The invention also relates to a transceiver and an integrated circuit comprising such a detection unit.

摘要： A method for a rate increase and a method for a rate reduction of a sampling input sequence into a sampling output sequence is provided. The sampling input sequence is subjected to signal processing. Signal processing maps a spreading with a first factor and an interpolation and a decimation with a second factor to generate the sampling output sequence with use of a counter. The counter and the signal processing are clocked with the higher rate, in each case, of the sampling input sequence or the sampling output sequence, respectively.
