    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： The identification and tracking of objects from captured sensor data relies upon statistical modeling methods to sift through large data sets and identify items of interest to users of the system. Statistical modeling methods such as Hidden Markov Models in combination with particle analysis and Bayesian statistical analysis produce items of interest, identify them as objects, and present them to users of the system for identification feedback. The integration of a training component based upon the relative cost of sampling sensors for additional parameters, provides a system that can formulate and present policy decisions on what objects should be tracked, leading to an improvement in continuous data collection and tracking of identified objects within the sensor data set.

    摘要： A device for detecting data synchronization in data communications includes pseudorandom noise (PN) lock circuits (101, 113, 127). The PN lock circuits (101, 113, 127) receive an input data stream (109). Each of the PN lock circuits (101, 113, 127) is time offset with respect to the other PN lock circuits. Each of the PN lock circuits (101, 113, 127) outputs a PN sequence responsive to the input data stream. For each PN lock circuit, there is provided a component (105, 117, 131) for comparing the PN sequence from the respective PN lock circuit to the input data stream, to determine whether the input data stream and the PN sequence are synchronized. An indication (107, 119, 133) that the data is synchronized is provided when the input data stream and the PN sequence are synchronized.

    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.
