Low-Power CMOS Wireless Communications: A Wideband CDMA System
Design focuses on the issues behind the development of a
high-bandwidth, silicon complementary metal-oxide silicon (CMOS)
low-power transceiver system for mobile RF wireless data
communications. In the design of any RF communications system,
three distinct factors must be considered: the propagation
environment in question, the multiplexing and modulation of user
data streams, and the complexity of hardware required to implement
the desired link. None of these can be allowed to dominate.
Coupling between system design and implementation is the key to
simultaneously achieving high bandwidth and low power and is
emphasized throughout the book. The material presented in Low-Power
CMOS Wireless Communications: A Wideband CDMA System Design is the
result of broadband wireless systems research done at the
University of California, Berkeley. The wireless development was
motivated by a much larger collaborative effort known as the
Infopad Project, which was centered on developing a mobile
information terminal for multimedia content - a wireless `network
computer'. The desire for mobility, combined with the need to
support potentially hundreds of users simultaneously accessing
full-motion digital video, demanded a wireless solution that was of
far lower power and higher data rate than could be provided by
existing systems. That solution is the topic of this book: a case
study of not only wireless systems designs, but also the
implementation of such a link, down to the analog and digital
circuit level.
