摘要： A method is provided for receiving a data frame in an ultrawide bandwidth network. In this method, a device receives an ultrawide bandwidth signal containing a data frame. The device then performs an acquisition operation during a first preamble in the data frame, and identifies a marker after the first preamble that indicates that the first preamble has ended. After this, the device performs a signal processing operation during a second preamble in the data frame. After the training, the device then receives a header in the data frame, and then receives a payload in the data frame. By having a marker between the two preambles, this method provides a receiving device with critical information regarding the timing of the preamble section of a frame.

摘要： An equalizer and corresponding methods is arranged and constructed to mitigate adverse effects of a wireless channel (300). The equalizer includes a delay line (503) coupled to an input signal (501) and comprising a delay circuit coupled to an output combiner (507) that is operable to provide an interim signal (g0 ... gN) and a feed forward circuit (505) coupled to the delay line and operable to provide a feed forward signal (506) that comprises a hard decision scaled according to a scaling factor corresponding to an estimate of channel parameters, wherein the output combiner is operable to combine the feed forward signal and the interim signal to provide an output signal (509) that is compensated for an adverse effect of the wireless channel on the input signal.

摘要： A process is provided for determining the distance between two devices by sending ranging packets between them. The local device sends a first ranging packet, which the remote device sends holds for a first hold time before sending a second ranging packet in return. The local device also sends a third ranging packet, which the remote device sends holds for a second hold time before sending a fourth ranging packet in return. If the second hold time is twice the first hold time, then the propagation time for signals between the two devices can be determined solely by time measurements made by the local device. For received signals, these time measurements can be adjusted to provide accurate time estimates for a direct line of sight signal, which corresponds to a shortest transmission distance between the two devices. The propagation time can then be used to determine distance between the devices.
摘要翻译：提供了一种通过在它们之间发送测距分组来确定两个设备之间的距离的过程。本地设备发送第一测距分组，远程设备在发送第二测距分组之前发送保持第一保持时间。本地设备还发送第三测距分组，远程设备在发送第四测距分组之前发送保持第二保持时间。如果第二保持时间是第一保持时间的两倍，则两个设备之间的信号的传播时间可以仅由本地设备进行的时间测量来确定。对于接收到的信号，可以调整这些时间测量值以便为直接视线信号提供准确的时间估计，其对应于两个装置之间的最短传输距离。然后可以使用传播时间来确定设备之间的距离。

摘要： A process is provided for determining the distance between two devices (310, 320) by sending ranging packets between them. The local device (310) sends a first ranging packet, which the remote device (320) sends holds for a first hold time before sending a second ranging packet in return. The local device (310) also sends a third ranging packet, which the remote device (320) sends holds for a second hold time before sending a fourth ranging packet in return. If the second hold time is twice the first hold time, then the propagation time for signals between the two devices (310, 320) can be determined solely by time measurements made by the local device. For received signals, these time measurements can be adjusted to provide accurate time estimates for a direct line of sight signal, which corresponds to a shortest transmission distance between the two devices. The propagation time can then be used to determine distance between the devices (310, 320).
