摘要： A multi-burst transmitter for ultra-wideband (UWB) communication systems generates a sequence of precisely spaced RF bursts from a single trigger event. There are two oscillators in the transmitter circuit, a gated burst rate oscillator and a gated RF burst or RF power output oscillator. The burst rate oscillator produces a relatively low frequency, i.e., MHz, square wave output for a selected transmit cycle, and drives the RF burst oscillator, which produces RF bursts of much higher frequency, i.e., GHz, during the transmit cycle. The frequency of the burst rate oscillator sets the spacing of the RF burst packets. The first oscillator output passes through a bias driver to the second oscillator. The bias driver conditions, e.g., level shifts, the signal from the first oscillator for input into the second oscillator, and also controls the length of each RF burst. A trigger pulse actuates a timing circuit, formed of a flip-flop and associated reset time delay circuit, that controls the operation of the first oscillator, i.e., how long it oscillates (which defines the transmit cycle).

摘要： The present invention is for a method and apparatus to improve an Ultra Wideband (UWB) digital receiver's performance sensitivity. A transmitted signal stream has each data bit having multiple identical modulated pulses separated by a constant time interval. The received signal stream is duplicated to create a second signal stream of identical modulated pulses to the original signal stream. The duplicated signal stream is delayed by the constant time interval between identical modulated pulses and the two signal streams correlated to form one signal stream which is detected to improve the sensitivity of the receiver.

摘要： Low-power transmitter and/or receiver devices are provided by sacrificing time and/or frequency diversity in exchange for lower power consumption. When channel conditions indicate that time and/or frequency spreading are unnecessary for transmissions, a transmitter may enter into a power-conservation mode in which transmissions are performed using a time gating scheme or a time repetition scheme. In the time gating scheme, symbols are transmitting just once, rather than a plurality of times, but with increased transmission power. In the time repetition scheme, copies of the same symbol are transmitted a plurality of times on the same frequency on different symbol transmission periods, instead of being retransmitted on different frequencies on different symbol transmission periods. Consequently, the symbol can be generated once and stored for subsequent retransmission, thereby allowing some of the transmitter/receiver chain components can be operated at a lower duty cycle or processing speed to conserve power.
摘要翻译：通过牺牲时间和/或频率分集来提供低功率发射机和/或接收机设备，以换取更低的功耗。当信道条件指示时间和/或频率扩展对于传输是不必要的时，发射机可以进入其中使用时间选通方案或时间重复方案执行传输的功率节约模式。在时间选通方案中，符号只传输一次，而不是多次，但是传输功率增加。在时间重复方案中，相同符号的副本在不同的符号传输周期上以相同频率发送多次，而不是在不同的符号传输周期上在不同的频率上重发。因此，可以生成符号一次并存储以用于随后的重传，从而允许一些发送器/接收器链组件可以以较低的占空比或处理速度操作以节省功率。

摘要： A pulse generator circuit is provided. The pulse generator circuit has an input adapted to receive an input electrical quantity and an output at which an output electrical quantity is made available. A transfer characteristic establishes a relationship between said input and said output electrical quantities. The pulse generator circuit is adapted to provide said output electrical quantity in the form of pulses having a predetermined shape, suitable to be used for UWB transmission. The transfer characteristic has substantially a same shape as that of said pulses. Moreover, a UWB modulating system exploiting the novel pulse generator is proposed.

摘要： The present invention provides a frequency synthesizer for a wireless communication system. The synthesizer includes an oscillator that generates an electronic signal as well as frequency dividers, frequency selectors and mixers. The signal generated by the oscillator is sequentially divided by the frequency dividers to produce a first group of frequencies, and the selectors and mixers are then capable of mixing the first group of frequencies according to instructions from control bits to produce a second group of frequencies which constitute UWB band frequencies. In this manner, the synthesizer can generate all 14 UWB band frequencies or particular UWB band groups using a single oscillator. One of the frequencies generated by the dividers can also be used as the baseband clock signal without requiring an additional frequency source.

The UWB system includes a baseband unit for modulating/demodulating an impulse data signal and generating a power management control signal using burst hopping information, and an RF transmitting/receiving unit for transmitting/receiving a wireless signal and alternating between power-on/off states according to the power management control signal generated from the baseband unit. The UWB system can reduce power consumption by applying power source to the RF transmitting/receiving unit only at a time interval in which an impulse signal having a short time period and constituting transmitting/receiving data exists.
