摘要： A circuit, system, and method for range finding between two nodes of a radio network, in particular in conformance with the industry standard IEEE 802.15.4. A mode for finding the range to a second node is initiated by the first node. A command for range finding with the address of the second node is transmitted from the first node to the second node in the mode for range finding. The second node is switched into the range finding mode by the command. A sequence is controlled by the command in the range finding mode. As a result of the control by the command, a first signal is transmitted by the first node in a transmission time window of the sequence and the first signal is received by the second node in an associated reception time window of the sequence, and a first phase value of the first signal is measured. As a result of the control by the command, a second signal is transmitted by the second node in a transmission time window of the sequence and the second signal is received by the first node in an associated reception time window of the sequence, and a second phase value of the second signal is measured. As a result of the control by the command, the first frequency of the first signal is changed by a frequency difference and the second frequency of the second signal is changed by the frequency difference in a subsequent time window of the sequence.

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： A receiver and method for operating a receiver, in particular of a radio network, is provided, whereby the receiver includes circuit blocks in a receive path for detecting a preamble of a received signal, and a controller for controlling a receive mode. Whereby at least some of the circuit blocks are designed to be capable of being turned on for a turn-on duration and turned off for a turn-off duration. Whereby, the controller is configured to alternately turn on at least some of the circuit blocks for the turn-on duration and off for the turn-off duration during the receive mode, wherein the turn-off duration is shorter than the preamble. Whereby, the controller is configured to compare a first measured value measured in the receive path to a first threshold, and the controller is configured to change the turn-on duration and/or the turn-off duration on the basis of a result of the comparison with the first threshold, and whereby the controller is configured to compare a second measured value to a second threshold in order to detect a valid signal of the preamble and, on the basis of a result of the comparison with the second threshold, to terminate the turn-off and to drive the portion of the circuit blocks into a turned-on state for a synchronization by means of the preamble.
