The U.C. Berkeley
Ultra-Wideband Group
Ultra-Wideband
(UWB) signaling promises a potentially revolutionary approach to radio
communication. By using pulses or waveforms compressed in time, frequency
energy may be spread over a very wide bandwidth to very low levels (even under the thermal noise
floor.) This may
allow UWB radios to share spectrum with existing narrowband broadcasters
without causing undue interference; thus creating many interesting
and novel application opportunities.
It
is the goal of this research group to investigate the design of UWB
transceivers realized in a conventional CMOS technology. Starting with
system considerations: link budgeting, channel and interference
modeling, communication distance vs. throughput, etc., we will explore
low-power architectural implementation trade-offs. Our overall objective
is the fabrication and demonstration of networked radios.
