UWB Preliminaries,ced. We then turn to UWB regulatory history and discuss Federal Communications Commission (FCC) first report and order. The dynamic spectrum access (DSA) is introduced and UWB is viewed as a way to implement DSA. Main attributes of UWB systems including transmit power, transmission capacity, link bu

UWB Channel Modeling,view the 802.15.3a channel model, aimed for high-throughput UWB applications with a range of up to 10 meters, in detail. Some of the weaknesses of 802.15.3a are addressed in another work. The modeling differences are revealed, enhancements are emphasized, and new parameter sets for three different e

Modulation Schemes and Multiple Access for Impulse Radio, presented and their performance is analyzed. To enable multiple accesses, a technique known as time hopping (TH) is introduced and it is integrated into various modulation techniques. Finally, the impact of the various antenna types on the transmitted and received UWB signal is investigated.
