TLDR
In this article, two UWB multiband systems, frequency hopping and Spectral Keying, have been described, both of which meet the stringent requirements provided by IEEE 802.15.3a.Abstract:
The recent FCC frequency allocation for UWB has generated a lot of interest in UWB technologies. There is 7,500 MHz of spectrum for unlicensed use. The main limitations are provided by the low-power spectral density and by the fact that the transmit signal must occupy at least 500 MHz at whole times. IEEE 802.15.3a is being developed for high-bit-rate PAN applications, and UWB is the most promising technology to support the stringent requirements: 110, 200, and 480 Mb/s. Two UWB multiband systems, frequency hopping and Spectral Keying, have been described in this article. Both systems meet the stringent requirements provided by IEEE 802.15.read more

A Method of Optical Ultra-Wide-Band Pulse Generation Based on XPM in a Dispersion Shifted Fiber
TL;DR: In this article, a method to generate UWB monocycle pulse using cross-phase modulation (XPM) in a dispersion shifted fiber (DSF) was proposed, in which the low-power continuous wave probe light is phase modulated by the high-power pump light because of the XPM in a disjoint fiber, then the following fiber Bragg grating (FBG) serves as a frequency discriminator, which convert the PM to IM.
