摘要： A first node of a radio network initiates a mode for finding the range to a second node. The first node transmits to the second node, with the address of the second node, a range finding command, which switches the second node into the range finding mode and controls a sequence. The first node transmits in a transmission time window a first signal, which is received by the second node in an associated reception time window, a first phase value of the first signal being measured. The second node transmits in a transmission time window a second signal, which is received by the first node in an associated reception time window, a second phase value of the second signal being measured. The first frequency is changed by a frequency difference and the second frequency is changed by the frequency difference in a subsequent time window of the sequence.

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 in a radio network and method for transit time measurement between a first node and a second node of a radio network is provided. A frame is transmitted by the first node, wherein the frame requires an acknowledgment of reception by the second node. A first point in time of the transmission of the frame is established by the first node by a time counter. The frame is received by the second node at a second point in time. The acknowledgment is transmitted by the second node to the first node at a third point in time, wherein the third point in time depends on the second point in time by a predetermined time interval between the second point in time and the third point in time. A fourth point in time is established by the first node by the time counter when the acknowledgment is received. The transit time or the change in transit time is determined from the first point in time established by the time counter and from the established fourth point in time and from the predetermined time interval.

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.

摘要： A method and device is provided for the detection of data symbols contained in a received radio signal, whereby each data symbol is allocated transmit-side a symbol value-specific PN sequence of successive PN chips in the chip clock and the PN sequences allocated to the data symbols are offset QPSK modulated. The method of the invention for incoherent detection provides for converting the received radio signal into a complex baseband signal sampled in the chip clock, generating a demodulated signal by differential demodulation of the complex baseband signal sampled in the chip clock, providing the derived sequences, calculating correlation results by correlating the demodulated signal with the derived sequences, and deriving, i.e., detecting, the values of the data symbols by evaluating the correlation results. In this case, each derived sequence is assigned to a PN sequence allocable transmit-side and includes derived chips, whose values in each case correspond to a logic linking of particular PN chips of the PN sequence allocable transmit-side that is assigned the derived sequence. The invention relates furthermore to a corresponding receiving unit.

摘要： An antenna diversity method and a corresponding communication device are disclosed that may be used in wireless LAN receivers. An AGC (Automatic Gain Control) unit controls a gain when processing signals received from antennae. A periodical switching process is performed between at least two antennae. During this periodical switching process, signals from each of the antennae are received alternately. The gain obtained by processing each received signal by means of the AGC unit is monitored and the obtained gain is compared with a predetermined threshold value. When for one of the at least two antennae the gain is below the predetermined threshold value, the periodical switching process is stopped and the antenna used at the time when stopping the periodical switching process is selected. This technique may provide an improved antenna diversity of low complexity, high performance and a short settling time.
