Turbo coding principles have found widespread applications in
information theory and, in part, have entered into mainstream
telecommunication theory and practice. These principles are used in
error control, detection, interference suppression, equalization,
and other communications-related areas. Turbo Codes: Principles and
Applications is intended for use by advanced level students and
professional engineers involved in coding and telecommunication
research. The material is organized into a coherent framework,
starting with basic concepts of block and convolutional coding, and
gradually increasing in a logical and progressive manner to more
advanced material, including applications. All algorithms are fully
described and supported by examples, and evaluations of their
performance are carried out both analytically and by simulations.
The book includes new and original material on a bidirectional SOVA
decoding algorithm, design of turbo codes based on the distance
spectrum, design of code-matched interleavers, performance on
fading channels, and a turbo trellis code modulation
scheme.Trellis-based and iterative decoding algorithms, along with
a comparison of algorithms based on their performance and
complexity, are discussed. Various practical aspects of turbo
coding, such as interleaver design, turbo codes on fading channels,
and turbo trellis-coded modulation, are presented. Turbo Codes:
Principles and Applications will be especially useful to practicing
communications engineers, researchers, and advanced level students
who are designing turbo coding systems, including encoder/decoder
and interleavers, and carrying out performance analysis and
sensitivity studies.
Satellite Communications: Mobile and Fixed Services is based on the
premise that designers of future satellite systems must take
account of the strong competition that satellites face from optical
fibers. In future years, satellites will continue to be
commercially viable media for telecommunications only if systems
designers take account of the unique features that satellites have
to offer. Accordingly, Satellite Communications places more
emphasis on satellite mobile services and broadcasting, and less
emphasis on fixed, point-to-point, high-capacity services than
traditional textbooks in the field. Also, an emphasis is given in
the book to design issues. Numerous illustative system design
examples and numerical problems are provided. The particular
attention given to methods of design of satellite mobile
communications systems should make it an indispensable resource for
workers in this field. The book also contains some recent results
of propagation modelling and system design studies which should be
of particular value to researchers and designers of satellite
systems for mobile communications services. Satellite
Communications is suitable for use as a textbook for advanced
courses on satellite communications, and is a valuable reference
for all those working in the field.

The spread-spectrum technique is becoming increasingly important in
wireless communication systems. In this work, the main advantages
of this techniques are outlined, describing its key elements,
presenting important code acquisition strategies for direct
sequences (DS) and frequency hopping (FH) systems, comparing
various code tracking loop systems, and detailing receiver
configurations based on CCD, SAW and DSP matched filters. The
authors also examine system capacity issues related to the CDMA
cellular network, and explain the CDMA overlay, packetized
transmission in CDMA networks, and the problems of multiuser
detection.
