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

Serialization of multi-band sequence keying for ultra wideband receiver architecture with reduced complexity and power consumption
TL;DR: In this paper, the transmission of a sequence keyed UWB symbol is partially serialized, and the reduced number of receiver paths are re-used during the reception of each of the partially serialised portions of a symbol and the local oscillator (312, 332, 334, 336, 336) output frequencies are changed for each of those portions.
