摘要： A circuit of a node of a radio network, and a method for distance measurement with a transceiver for receiving a first signal with a first frequency by downmixing to an intermediate frequency, with a phase measurement unit, which is set up to determine a first value of a first phase for a first frequency value of the first frequency. The transceiver is formed to transmit a second signal with a first frequency value of a second frequency for determining a first value of a second phase. The control circuit is set up to change the first frequency and the second frequency, in that a second frequency value of the first frequency and the first frequency value of the first frequency have a frequency difference, and whereby a second frequency value of the second frequency and the first frequency value of the second frequency have the frequency difference. The phase measurement unit is set up to determine a second value of the first phase for the second frequency value of the first frequency. The first frequency of the first signal and the second frequency of the second signal are spaced apart by an amount of the intermediate frequency.

摘要： An improved data communication receiver technique is provided which avoids demodulation errors due to abrupt phase changes. A receiver is provided for processing an incoming digitized signal. The receiver comprises a pre-processing portion, a phase error correction unit and a signal evaluation unit. The pre-processing portion is adapted to process the digitized signal for providing a non-coherent pre-processed signal. The phase error correction unit is adapted to correct a phase error of the non-coherent pre-processed signal and output a coherent signal. The signal evaluation unit is adapted to extract information from the non-coherent pre-processed signal and to output a data signal representing the extracted information. The phase error correction unit and said signal evaluation unit are configured to operate simultaneously for a predetermined time.

摘要： A method for detecting occupation of an adjacent channel by a signal with the aid of a complex-valued bandpass signal having an information channel component and/or an adjacent channel component. In accordance with the invention, a) a real-valued bandpass signal is derived in that the complex-valued bandpass signal is filtered and the real component is produced from the filtered signal, b) the real-valued bandpass signal is transposed into a first baseband signal, c) the first baseband signal is filtered so that spectral components influenced by the information channel component are suppressed, and d) the first filtered signal is evaluated and a binary occupation signal is generated to indicate the occupation of the adjacent channel as a function of the evaluated first filtered signal. The invention further discloses a corresponding device for detecting occupation, as well as a transmitting/receiving device and an integrated circuit having such a device.
