摘要

A method for demodulating and detection of with the aid of a diversity - receiving system received spread - spectrum - signals of a from a subscriber is transmitted spread - spectrum - transmission signal in the case of a radio communication system with random - access - access,– in the case of the at least two different due to multipath propagation, spread - spectrum - signals with the aid of at least two contained in the diversity - emfangssystem exciter systems are received,– in the case of which a first spread - spectrum - signal to a first complex data stream and a second spread - spectrum - signal to a second complex data stream to be processed,– in the case of these two data streams being divided up in such a way that they in each case alternately in succession at inputs of a demodulator associated correlator fingers to the formation of a demodulation result, wherein the demodulation result characterizing portions of the first and second data stream into successively change, and the demodulation result is evaluated by means of a detector, and– in the case of which each individual spread - spectrum - signal for the formation of the respective data stream having a complex osf oversampling factor is scanned, the simple signal bandwidth of the spread - spectrum - signal corresponds to.
