This book is intended for courses at least at Masters level to provide an introduction
to the field of signal processing in telecommunications. The text therefore
deals mainly with source coding, channel coding, modulation and demodulation.
Adaptive channel equalisation, the signal processing aspects of adaptive antennas
as well as multi-user detectors for CDMA are also included. Shorter sections on
link budget, synchronising and cryptography are also included. Network aspects
are not discussed and very little is given about wave propagation.
The concept and theory of signals and systems are needed in almost all electrical
engineering fields and in many other engineering and scientific disciplines as well. In this
chapter we introduce the mathematical description and representation of signals and
systems and their classifications. We also define several important basic signals essential to
Development of packet-switched data communication networking
technologies has been rapid in recent years, a phenomenon made
possible by the open standardization process and the potential
new territories for intellectual property creation. As a consequence,
new ways of creating services have been devised, bringing more
flexibility as compared to traditional telecommunications schemes.
