摘要： A method for conveying application data via carrierless ultra wideband wireless signals, and signals embodied in a carrierless ultra wideband waveform. Application data is encoded into wavelets that are transmitted as a carrierless ultra wideband waveform. The carrierless ultra wideband waveform is received by an antenna, and the application data is decoded from the wavelets included in the waveform. The waveforms of the signals include wavelets that have a predetermined shape that is used to modulate the data. The signals may convey, for example, Web pages and executable programs between mobile devices. The signals are low power and can penetrate obstructions making them favorable for use with a wireless node of a network.

摘要： A method is provided for transmitting data. A first device generates a first signal having a first duty cycle, comprising a first gated-on portion and a first gated-off portion in a time slot; and a second device generates a second signal having second duty cycle, comprising a second gated-on portion and a second gated-off portion in the same time slot. The first gated-on portion is generated during a first segment of the time slot and the first gated-off portion is generated during a second segment of the time slot, while the second gated-on portion is generated during the second segment and the second gated-off portion is generated during the first segment. Media access control (MAC) can be used to further define positions within time slots and provide error correction, power control, and the like. A preamble can be transmitted at an increased power level to facilitate acquisition.

摘要： A system and method for fast synchronization of an incoming signal with a UWB receiver rapidly. The present invention synchronizes with a UWB receiver with an incoming signal. The present invention correlates a local pulse generated at the receiver with the incoming signal, finds a phase angle in the correlation function that would correspond to a high signal to noise ratio, thereby matching the receiver to the incoming signal phase, and operates the receiver at that phase. Exemplary options of fast synchronization include using multiple detection arms to compare one parameter of the correlation function to a predetermined threshold.

摘要： A method is provided for offsetting a reference frequency of a quadrature reference clock signal. A quadrature reference clock (110) generates the quadrature reference clock signal at the reference frequency, while a quadrature variable offset clock (130) generates a quadrature clock signal at a base offset frequency based on a base offset value it receives from a control circuit (560). The base offset value can be determined in many ways, including reading it from a local memory (910) or receiving it from a remote device (1010). A polyphase mixer (140) performs a polyphase mixing operation between the quadrature reference clock signal and the offset clock signal to generate an agile clock signal having an agile clock frequency equal to the reference frequency plus the base offset frequency. If desired, the method can revise the offset frequency based on actual conditions and determine a corresponding revised offset value (920, 1020).
