摘要： A system and method are provided that can detect any part of a multipath impulse radio signal. More specifically, the method compares a template pulse train and the multipath impulse radio signal to obtain a comparison result. The system performs a threshold check on the comparison result. If the comparison result passes the threshold check, the system locks onto any part of the multipath impulse radio signal including a direct path part and at least one multipath reflection part. The system may also perform a quick check, a synchronization check, and/or a command check of the multipath impulse radio signal.

摘要： Time is transferred from an ultra wideband (UWB) transmitter to UWB receiver by transmitting a signal structure having an associated timing reference point together with a time value for the timing reference point. The UWB receiver receives the timing signal structure by synchronizing a receiver time base to the signal structure, demodulating the time value information, and using the demodulated time value information to set a receiver clock value. Propagation delay information is used to adjust the receiver clock value by advancing the receiver clock value to account for the propagation delay. In one embodiment, propagation delay is determined from a known distance between the transmitter and receiver. In another embodiment, the transmitter and receiver are part of a two-way link wherein propagation delay is measured by round trip timing measurements.

摘要： A system for evaluating properties of materials by probing the materials using ultra wideband signals wherein the probing may be by transmission or by reflection of radiated ultra wideband signals. Received signals may be evaluated by determining signal characteristics including reflection coefficient, transmission attenuation, multipath decay profile, and signal scattering coefficient. Received signals are evaluated using deconvolution and Fourier processing. Test chamber characteristics and boundary reflections may be removed to yield bulk material properties. The system may be calibrated by employing empirical signal measurements from materials with known properties measured by reference techniques.

摘要： A transmit-rake apparatus includes at least one pulse generator that provides a plurality of pulses with selected signal properties so as to improve the signal-to-noise ratio at a receiver. The signal properties may include pulse timing, amplitude, polarity, and pulse shape. The transmit-rake apparatus may use a multipath analyzer, receive multipath or signal-quality information, or use a combination of those techniques. The multipath analyzer may include a scanning receiver to generate a scan of the multipath response. Correlation of the multipath response with a model pulse shape may be used to establish pulse position and amplitude. Iteration based on link performance measurements may be used to select or refine pulse properties. A method is disclosed to vary the selection of pulses to improve the spectrum.

摘要： A method for specifying pulse characteristics applies codes having pre-defined characteristics to a layout. The layout can be sequentially subdivided into at least first and second components that have the same or different sizes. The method applies a first code having first pre-defined properties to the first component and a second code having second pre-defined properties to the second component. The pre-defined properties may relate to the auto-correlation property, the cross-correlation property, and spectral properties, as examples. The codes can be used to specify subcomponents within a frame, and characteristic values (range-based, or discrete) within the subcomponents.

摘要： Apparatuses, systems and methods for transmitting and receiving modulated impulse radio signals. An impulse radio receiver includes a time base, a precision timing generator, a template generator, a delay, first and second correlators, a data detector and a time base adjustor. The time base produces a periodic timing signal that is used by the precision timing generator to produce a timing trigger signal. The template generator uses the timing trigger signal to produce a template signal. A delay receives the template signal and outputs a delayed template signal. When an impulse radio signal is received, the first correlator correlates the received impulse radio signal with the template signal to produce a first correlator output signal, and the second correlator correlates the received impulse radio signal with the delayed template signal to produce a second correlator output signal. The data detector produces a data signal based on at least the first correlator output signal. The time base adjustor produces a time base adjustment signal based on at least the second correlator output signal. The time base adjustment signal is used to synchronize the time base with the received impulse radio signal.

摘要： Impulse radio links are applied as the wireless means for allowing the separation of traditionally wired audio/video displays from their sources of information. This wireless separation affords an enhanced information system architecture in which a remote user interface can select from a variety of information and/or entertainment sources. The data bandwidth and superior performance of impulse radios in a high RF multipath environment open these previously hardwired interfaces to a wireless implementation. For example, untethered television is provided.

摘要： A system and method for highly selective intrusion detection using a sparse array of time modulated ultra wideband (TM-UWB) radars. Two or more TM-UWB radars are arranged in a sparse array around the perimeter of a building. Each TM-UWB radar transmits ultra wideband pulses that illuminate the building and the surrounding area. Signal return data is processed to determine, among other things, whether an alarm condition has been triggered. High resolution radar images are formed that give an accurate picture of the inside of the building and the surrounding area. This image is used to detect motion in a highly selective manner and to track moving objects within the building and the surrounding area. Motion can be distinguished based on criteria appropriate to the environment in which the intrusion detection system operates.
