Abstract:
1. A receiving device for a multipoint-to-point network, wherein the multipoint-to-point network is a synchronous multipoint-to-point CDMA network, containing a first unit for receiving and detecting a communications signal, in particular a CDMA-coded communications signal, and a second unit for receiving and detecting a coded synchronization signal, wherein the second unit contains a series circuit of a demodulator and a logical correlator and is used for demodulating and detecting the coded synchronization signal, said coded synchronization signal having a signal level which is lower than a signal level of the communications signal and/or is coded using a code which differs from a code of the communications signal, characterized in that the second unit contains two logical correlators connected in parallel for correlating the synchronization signal and two demodulators, that a first demodulator is connected in an incoming circuit to a first correlator and a second demodulator is connected in an incoming circuit to a second correlator, that the first demodulator is driven by a first clock pulse and that the second demodulator is driven by a second clock pulse, the second clock pulse having the same clock pulse frequency as the first clock pulse and a preset phase difference compared with the first clock pulse.
