Product Description:
Digital Communications is a classic book in the area that is designed to be used as a senior or graduate level text. The text is flexible and can easily be used in a one semester course or there is enough depth to cover two semesters. Its comprehensive nature makes it a great book for students to keep for reference in their professional careers.
This all-inclusive guide delivers an outstanding introduction to the analysis and design of digital communication systems. Includes expert coverage of new topics: Turbocodes, Turboequalization, Antenna Arrays, Digital Cellular Systems, and Iterative Detection. Convenient, sequential organization begins with a look at the history and classification of channel models and builds from there.
It is a pleasure to welcome Professor Masoud Salehi as a coauthor to the fifth edition
of Digital Communications. This new edition has undergone a major revision and
reorganization of topics, especially in the area of channel coding and decoding. A new
chapter on multiple-antenna systems has been added as well.
The book is designed to serve as a text for a first-year graduate-level course for
students in electrical engineering. It is also designed to serve as a text for self-study
and as a reference book for the practicing engineer involved in the design and analysis
of digital communications systems. As to background, we presume that the reader has
a thorough understanding of basic calculus and elementary linear systems theory and
prior knowledge of probability and stochastic processes.
Chapter 1 is an introduction to the subject, including a historical perspective and
a description of channel characteristics and channel models.
Chapter 2 contains a review of deterministic and random signal analysis, including
bandpass and lowpass signal representations, bounds on the tail probabilities of random
variables, limit theorems for sums of random variables, and random processes.
Chapter 3 treats digital modulation techniques and the power spectrum of digitally
modulated signals.
Chapter 4 is focused on optimum receivers for additive white Gaussian noise
(AWGN) channels and their error rate performance. Also included in this chapter is
an introduction to lattices and signal constellations based on lattices, as well as link
budget analyses for wireline and radio communication systems.
Chapter 5 is devoted to carrier phase estimation and time synchronization methods
based on the maximum-likelihood criterion. Both decision-directed and non-decision-
directed methods are described.
Chapter 6 provides an introduction to topics in information theory, including
lossless source coding, lossy data compression, channel capacity for different channel
models, and the channel reliability function.
Chapter 7 treats linear block codes and their properties. Included is a treatment
of cyclic codes, BCH codes, Reed-Solomon codes, and concatenated codes. Both soft
decision and hard decision decoding methods are described, and their performance in
AWGN channels is evaluated.
Chapter 8 provides a treatment of trellis codes and graph-based codes, includ-
ing convolutional codes, turbo codes, low density parity check (LDPC) codes, trel-
lis codes for band-limited channels, and codes based on lattices. Decoding algo-
rithms are also treated, including the Viterbi algorithm and its performance on AWGN
channels, the BCJR algorithm for iterative decoding of turbo codes, and the sum-product
algori thm.
Chapter 9 is focused on digital communication through band-limited channels.
Topics treated in this chapter include the characterization and signal design for band-
limited channels, the optimum receiver for channels with intersymbol interference and
AWGN, and suboptimum equalization methods, namely, linear equalization, decision-
feedback equalization, and turbo equalization.
Chapter 10 treats adaptive channel equalization. The LMS and recursive least-
squares algorithms are described together with their performance characteristics. This
chapter also includes a treatment of blind equalization algorithms.
Chapter 11 provides a treatment of multichannel and multicarrier modulation.
Topics treated include the error rate performance of multichannel binary signal and
M -ary orthogonal signals in AWGN channels; the capacity of a nonideallinear filter
channel with AWGN; OFDM modulation and demodulation; bit and power alloca-
tion in an OFDM system; and methods to reduce the peak-to-average power ratio in
OFDM.
Chapter 12 is focused on spread spectrum signals and systems, with emphasis
on direct sequence and frequency-hopped spread spectrum systems and their perfor-
mance. The benefits of coding in the design of spread spectrum signals is emphasized
throughout this chapter.
Chapter 13 treats communication through fading channels, including the charac-
terization of fading channels and the key important parameters of multipath spread and
Doppler spread. Several channel fading statistical models are introduced, with empha-
sis placed on Rayleigh fading, Ricean fading, and N akagami fading. An analysis of the
performance degradation caused by Doppler spread in an OFDM system is presented,
and a method for reducing this performance degradation is described.
Chapter 14 is focused on capacity and code design for fading channels. After intro-
ducing ergodic and outage capacities, coding for fading channels is studied. Bandwidth-
efficient coding and bit-interleaved coded modulation are treated, and the performance
of coded systems in Rayleigh and Ricean fading is derived.
Chapter 15 provides a treatment of multiple-antenna systems, generally called
multiple-input, multiple-output (MIMO) systems, which are designed to yield spatial
signal diversity and spatial multiplexing. Topics treated in this chapter include detection
algorithms for MIMO channels, the capacity of MIMO channels with A WGN without
and with signal fading, and space-time coding.
Chapter 16 treats multiuser communications, including the topics of the capacity
of multiple-access methods, multiuser detection methods for the uplink in CDMA
systems, interference mitigation in multiuser broadcast channels, and random access
methods such as ALOHA and carrier-sense multiple access (CSMA).
With 16 chapters and a variety of topics, the instructor has the flexibility to design
either a one- or two-semester course. Chapters 3, 4, and 5 provide a basic treatment of
digital modulation/demodulation and detection methods. Channel coding and decoding
treated in Chapters 7, 8, and 9 can be included along with modulation/demodulation
in a one-semester course. Alternatively, Chapters 9 through 12 can be covered in place
of channel coding and decoding. A second semester course can cover the topics of
communication through fading channels, multiple-antenna systems, and multiuser com-
munications.
The authors and McGraw-Hill would like to thank the following reviewers for their
suggestions on selected chapters of the fifth edition manuscript:
Paul Salama, Indiana University/Purdue University, Indianapolis; Dimitrios Hatz-
inakos, University of Toronto, and Ender Ayanoglu, University of California, Irvine.
Finally, the first author wishes to thank Gloria Doukakis for her assistance in typing
parts of the manuscript. We also thank Patrick Amihood for preparing several graphs
in Chapters 15 and 16 and Apostolos Rizos and Kostas Stamatiou for preparing parts
of the Solutions Manual.
