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.

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 transmitter-receiver circuit and a method for distance measurement between a first node and a second node of a radio network is provided, wherein a mode of the first node and a mode of the second node are switched from a normal mode for communication in the radio network to a mode for distance measurement, wherein, in the mode for distance measurement for a transit time measurement, a radio signal is transmitted by the first node and received by the second node and a radio signal is transmitted by the second node and received by the first node and a first distance value is determined by measuring the transit time of the radio signals. In the mode for distance measurement, for a phase measurement an unmodulated carrier signal is transmitted as a radio signal by the first node and received by the second node and an unmodulated carrier signal is transmitted as a radio signal by the second node and received by the first node and a second distance value is determined by measurement and calculation from four values of the phases for different frequencies of the radio signals. Whereby, the distance between the first node and the second node is calculated from the first distance value of the transit time measurement and the second distance value of the phase measurement.

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.
