ABSTRACT
Ultra-Wideband (UWB) technology is gaining increasing interest for
its potential application to short-range indoor wireless communica-
tions. Utilizing ultra-short pulses, UWB baseband transmissions
enable rich multipath diversity, and can be demodulated with low
complexity receivers. Compliance with the FCC spectral mask, and
interference avoidance to, and from, co-existing narrow-band ser-
vices, calls for judicious design of UWB pulse shapers. This paper
introduces pulse shaper designs for UWB radios, which optimally
utilize the bandwidth and power allowed by the FCC spectral mask.
The resulting baseband UWB systems can be either single-band, or,
multi-band. More important, the novel pulse shapers can support
dynamic avoidance of narrow-band interference, as well as efficient
implementation of fast frequency hopping, without invoking analog
carriers.
