摘要： A PHY entity for a UWB system utilizes the unlicensed 3.1-10.6 GHZ UWB band, as regulated in the United States by the Code of Federal Regulation, Title 47, Section 15. The UWB system provides a wireless pico area network (PAN) with data payload communication capabilities of 55, 80, 110, 160, 200, 320 and 480 Mb/s. The UWB system employs orthogonal frequency division multiplexing (OFDM) and uses a total of 122 sub-carriers that are modulated using quadrature phase shift keying (QPSK). Forward error correction coding (convolutional coding) is used with a coding rate of 11/32, 1/2, 5/8 and 3/4.

摘要： A technique for generating carrier frequencies with fast hopping capability associated with multiband systems for ultra wideband applications. The technique employs a single VCO 20 that is locked in a PLL 30. The output of this VCO 20 is divided in the frequency domain. The divided frequencies thus obtained are combined in a single-sideband manner to obtain various other frequencies. The single-sideband combination requires open loop operations such as multiplication and addition or subtraction to implement, and hence is very fast. The VCO center frequency is not disturbed in the process. Since the required frequencies are generated in an open-loop fashion, instead of inside a PLL, the speed is increased by orders of magnitude.
摘要翻译：用于产生具有与用于超宽带应用的多频带系统相关联的具有快速跳变能力的载波频率的技术。该技术采用锁定在PLL 30中的单个VCO 20。该VCO 20的输出在频域中被划分。这样获得的划分频率以单边带方式组合以获得各种其它频率。单边带组合需要开环操作，例如乘法和加法或减法来实现，因此非常快。 VCO中心频率在此过程中不受干扰。由于所需的频率是以开环方式产生的，而不是在PLL内部，速度增加了数量级。

A preferred embodiment comprises an ultra-wideband (UWB) device that makes use of a portion of the UWB frequency range to help provide good performance in the presence of interferers. Additionally, since only a portion of the UWB frequency range is used, multiple devices can simultaneously transmit and receive by using different portions of the UWB frequency range.

摘要： An efficient bit interleaving scheme for a multi-band OFDM ultra-wideband (UWB) system. The encoded bits of the multi-band OFDM system are interleaved within each OFDM symbol and across OFDM symbols. The bit interleaving scheme minimizes performance degradation due to groups of contiguous OFDM tones experiencing a poor SNR caused by the frequency selective channel, exploits the frequency diversity across sub-bands, randomizes the effect of co-channel interference from simultaneously operating un-coordinated piconets, and randomizes the impact of generic narrow-band interferers present within the UWB spectrum.
