    • A system used for calibrating a direction-finding system. A device may include a signal receiver array. The signal receiver array may be utilized to determine the direction of arrival for signals emitted by other devices, and therefore, may be used to resolve the direction towards another device using the received signal. For example, an external tag may be utilized to emit a wireless signal usable inducing a response in each signal receiver of the signal receiver array. The device may also include one or more sensors usable in determining device orientation and/or a change in device orientation. The combined signal receiver response information and orientation information may be recorded at various instants as the device is moved for use in calibrating the antenna array.
    • 用于校准测向系统的系统。 设备可以包括信号接收器阵列。 信号接收器阵列可以用于确定由其他设备发射的信号的到达方向,并且因此可以用于使用接收到的信号来解析朝向另一设备的方向。 例如,可以使用外部标签来发射可用于在信号接收器阵列的每个信号接收器中引起响应的无线信号。 该装置还可以包括可用于确定装置取向和/或装置取向变化的一个或多个传感器。 组合的信号接收机响应信息和取向信息可以在设备移动以用于校准天线阵列时在各种时刻被记录。

    • An exemplary method includes: obtaining I and Q complex signal parameters of signals received from a mobile tag at each of at least three antenna elements forming part of a positioning device; extracting an identifier modulated onto the signals received from the mobile tag; and transmitting the I and Q complex signal parameters and the identifier-to allow a position calculating device to calculate a bearing of the mobile tag from the positioning device, wherein transmitting the I and Q complex signal parameters and the identifier comprises the positioning device wirelessly broadcasting the I and Q complex signal parameters and the identifier. An exemplary apparatus and computer readable medium configured to perform the method are also disclosed.

    • A system for implementing a positioning functionality. An apparatus (e.g. a directional transceiver) (706) may receive a signal (704) for positioning and measure characteristics associated with the received signal (704). If the directional transceiver (706) then determines that the received signal (704) comprises calculator identifier information, the apparatus may forward the measured characteristics based on the calculator identifier information. Otherwise, the directional transceiver (706) may forward the measured characteristics to a buffer (712). From the perspective of the apparatus (700) transmitting the signal (704) for positioning, a determination may be made as to whether calculator identifier information is known. If determined to be known, the transmitting apparatus (700) may include the calculator identifier information in the signal (704) for positioning. Otherwise, the other apparatus may transmit the signal (704) for positioning without any calculator identifier information.
    • 一种用于实现定位功能的系统。 装置(例如定向收发器)(706)可以接收用于定位和测量与接收信号(704)相关联的特性的信号(704)。 如果定向收发器(706)确定接收信号(704)包括计算器标识符信息,则装置可以基于计算器标识符信息转发测量的特性。 否则,定向收发器(706)可以将所测量的特性转发到缓冲器(712)。 从发送用于定位的信号(704)的装置(700)的角度来看,可以确定计算器标识符信息是否已知。 如果确定为已知,发送装置(700)可以包括用于定位的信号(704)中的计算器标识符信息。 否则,其他装置可以发送用于定位的信号(704)而没有任何计算器标识符信息。
