FOREWORD
Well over a billion people are currently using cellular telephones, and
this number is expected to grow to over two billion in the next few
years. It is remarkable that a device that was considered a high-
technology "toy" just a few years ago is now an indispensable feature
of modern life. One of the key reasons for this remarkable trans-
formation is the integration of all the radio functions of a cellular
telephone onto a single inexpensive piece of silicon. This achievement
is a result of innovations in design and process technology that allowed
formerly discrete and separate devices to be integrated onto a common
substrate.
Now that this integration has been accomplished, the next challenge
is to make these radio functions adaptive to their environment. For
example, a cellular telephone of the future will be able to "sense" its
environment, and configure its radio functions to optimize the perfor-
mance - and minimize the battery drain - for that environment; when
the cellular telephone is close to a base station and is in a low
interference environment it will reduce its power consumption for the
relaxed performance requirements. Conversely, when it is far from the
base station and in a high interference environment, the radio will be
adjusted accordingly.
This "adaptive" feature of wireless communications devices is just
today becoming a reality, and this book represents one of the first
comprehensive treatments of the subject. Adaptive radio transceivers
require a comprehensive theoretical framework in order to optimize
their performance. The authors provide this framework with their
discussion of joint optimization of Noise Figure and Input Intercept
Point in receiver systems. They then provide original techniques
to optimize voltage controlled oscillators and low-noise amplifiers
to minimize their power consumption while maintaining adequate
system performance. The experimental results that they present at the end
of the book confirm that utility of their techniques.
