摘要：The device for receiving signals which have carrier frequencies and codes, saidsignals being navigation or communication signals, has multiple individual antennas (114)for receiving a signal, each individual antenna (114) having an antenna output (116) atwhich the received signal is present. Furthermore, the device is provided with an analogpreprocessing unit (122) for preprocessing the signals received by the individual antennas(114), said preprocessing unit (122) having signal transmitting and signal preprocessingchannels (124) which are assigned to the individual antennas (114), and the device isprovided with a digital signal processor (134). The device additionally has a calibrationsignal generating unit (148) for generating a calibration signal which, like the signalsreceived by the individual antennas (114), has a carrier frequency and a code and which isused for calibrating the propagation time and the phase of the signal transmission paths.Additionally, a reference frequency generating unit (150) is also provided that generatesa reference frequency with which the analog preprocessing unit (122), the digital signalprocessor (134), and/or the calibration signal generating unit (148) can be operatedand/or on the basis of which other operating frequencies with a specifiable relationshipto the reference frequency can be generated in order to operate the analog
preprocessing unit (122), the digital signal processor (134), and/or the calibration signalgenerating unit (148).
