摘要： The method according to the present disclosure introduces acquisition and tracking modes for a mobile device assisted multilateration based localization method. The method is employed for determining a relative time difference between a positioning reference cell and at least two other detectable positioning cells. The method includes in a mobile device attempting to detect a reference signal of a positioning cell to determine the timing of a detectable positioning cell by either applying sliding window approach to acquire the positioning cell or a single window approach to track the positioning cell. The sliding window approach within a search window is applied to acquire the positioning cell when a coarse timing of the positioning cell has not yet been achieved. A coarse timing is said to be achieved when only a fine timing is further required. This is the case when the remaining search window has a size that is not larger than the capture range capability of the mobile device. Conversely, a single window approach is applied to track the positioning cell when a coarse timing of the positioning cell has been achieved or when the search window is not larger than a capture range capability of the mobile device. Ultimately, the method includes computing the time difference between the positioning reference cell and the at least two other detectable positioning cells.
摘要翻译：根据本公开的方法引入了用于基于移动设备的多点定位方法的获取和跟踪模式。该方法用于确定定位参考单元与至少两个其它可检测定位单元之间的相对时间差。该方法包括在移动设备中尝试通过应用滑动窗口方法来获取定位单元或单一窗口方法来跟踪定位单元来检测定位单元的参考信号以确定可检测定位单元的定时。当定位单元的粗略定时尚未实现时，应用搜索窗口内的滑动窗口方法来获取定位单元。据说仅在进一步需要精细定时时才实现粗略定时。当剩余搜索窗口的尺寸不大于移动设备的捕获范围能力时，就是这种情况。相反，当已经实现定位单元的粗略定时或者当搜索窗口不大于移动设备的捕获范围能力时，应用单窗口方法来跟踪定位单元。最终，该方法包括计算定位参考小区与至少两个其它可检测定位小区之间的时间差。

摘要： The invention is directed to methods for radio frequency spectral analysis. Accordingly, flight instructions are executed on a first UAV to fly in a first flight pattern relative to a signal source. The first UAV detects radio signal(s) from the signal source and associated signal data. Flight instructions are concurrently executed on a second UAV to fly in a second flight pattern, relative to the first flight pattern of the first UAV. The second UAV also detects radio signal(s) from the signal source and associated signal data. The stored signal data from the drones may then be processed for visualization.

摘要： Methods and apparatus for calibrating received signal measurements in a digital subscriber line (DSL) device are disclosed. In an exemplary method, a received signal level is measured for each of one or more subcarriers of a digital subscriber line signal and converted into a corresponding measured power level. A corrected received power level is calculated as a function of the measured power level, a reference input impedance value, a nominal loop impedance value, and a pre-determined input impedance value for the DSL device.
