This book serves as an easily accessible reference for wireless digital communication systems.
Topics are presented with simple but non-trivial examples and then elaborated with their
variations and sophistications. It includes numerous examples and exercises to illustrate key
points. The book emphasizes both practical problem solving and a thorough understanding of
fundamentals aiming to realize the complementary relationship between practice and theory.
Though the author emphasize wireless radio channels the fundamentals that are covered are
useful to different channels - digital subscriber line coax power lines optical fibers and
even Gigabit serial interconnection. This book is the outgrowth of the author's hands-on
experience in the telecommunication systems industry as a research and development engineer. It
is written primarily for practitioners of wireless digital communication systems - engineers
and technical leaders and managers - and for digital communication systems in general including
new comers like graduate students and upper-division undergraduate students. The material in
chapters 5(OFDM) 6(Channel coding) 7(Synchronization) and 8(Transceivers) contains something
new not explicitly available in typical textbooks and useful in practice. For example in
Chapter 5 all known orthogonal frequency division multiplex signals are formulated based on
pulse shape and thus flexible e.g. unlike currently predominant symbol block transmission it
can be serial transmission. In Chapter 6 we emphasize practical applications of powerful error
coding such as LDPC to higher order modulations fading and non-linearity problem. In Chapter
7 new digital timing detectors are suggested for small access bandwidth shaping pulse and a
digital quadrature imbalance correction is also included along with digital carrier phase
recovery. In Chapter 8 low IF digital image cancelling transceiver is treated in detail so
that practical implementation can be readily done with advantages.
