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).
摘要翻译：提供了一种用于抵消正交参考时钟信号的参考频率的方法。正交参考时钟（110）以参考频率产生正交参考时钟信号，而正交可变偏移时钟（130）基于从控制电路接收的基本偏移值以基本偏移频率产生正交时钟信号（ 560）。基本偏移值可以以许多方式确定，包括从本地存储器（910）读取或从远程设备（1010）接收基本偏移值。多相混合器（140）在正交参考时钟信号和偏移时钟信号之间执行多相混合操作，以产生具有等于参考频率加上基极偏移频率的敏捷时钟频率的敏捷时钟信号。如果需要，该方法可以根据实际条件修改偏移频率，并确定对应的修正偏移值（920,1020）。

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： A method apparatus are provided for mitigating spectral lines in a wireless signal. First a code word is generated that is made up of a plurality of binary or ternary encoded pulses. Then a plurality of code-word-modulated wavelets are generated in response to the code word. These wavelets can be Gaussian monopulses, repeated cycles of a sine wave, or other shaped impulse signals. The plurality of code-word-modulated wavelets are then modulated with a bit of transmit data to form a plurality of data-modulated wavelets. This modulation serves to whiten the signals since the transmit data is effectively random. Finally, the plurality of data-modulated wavelets are transmitted to a remote device.

摘要： A transmitter (910) encodes and a receiver (920) decodes a signal using M-ary bi orthogonal keying. The transmitter (910) receives a stream of data bits and breaks a number of data bits off the stream to form a bit sequence. The transmitter (910) then chooses a code that corresponds to the bit sequence, and transmits the chosen code. The receiver (920) receives the code and correlates it with all possible codes to generate a plurality of correlation values. It then compares these correlation values to determine which code was sent, and therefore what the received bit sequence is. The codes are mutually orthogonal, and prefereable include a plurality of code words and an equal number of code word inverses. The code may be scrambled by multiplying it with a pseudo-random sequence at the transmitter, and descrambled by multiplying it by the same pseudo-random sequence at the receiver.

摘要： A planar ultra wide bandwidth (UWB) antenna that provides integration of electronics is disclosed. The antenna has a first balance element that is connected to a terminal at one end. A second balance element is connected to another terminal at one end. The second balance element has a shape that mirrors the shape of the first balance element such that there is a symmetry plane where any point on the symmetry plane is equidistant to all mirror points on the first and second balance elements. Each of the balance elements is made of a generally conductive material. A triangular shaped ground element is situated between the first balance element and the second balance element with an axis of symmetry on the symmetry plane, and oriented such that the base of the triangle is towards the terminals. Accordingly, the ground element and each of the balance elements form two tapered gaps which widen and converge at the apex of the ground element as the taper extends outwardly from the terminals. Under this arrangement, sensitive UWB electronics can be housed within the perimeter of the ground element, thereby eliminating transmission line losses and dispersion, and minimizing and system ringing. A resistive loop connected between the first and second balance elements extends the low frequency response and improves the VSWR. A connection of an array of elements is disclosed that provides a low-frequency cutoff defined by the array size rather than the element size.
