Preface
This new fourth edition of Principles of Electronic Communication Systems is fully
revised and updated to make it one of the most current textbooks available on wireless,
n etworking, and other communications technologies. Because the i eld of electronic
c ommunications changes so fast, it is a never-ending challenge to keep a textbook up to
date. While principles do not change, their emphasis and relevance do as technology
evolves. Furthermore, students need not only a i rm grounding in the fundamentals but
also an essential understanding of the real world components, circuits, equipment, and
systems in everyday use. This latest edition attempts to balance the principles with an
overview of the latest techniques.
A continuing goal of this latest revision is to increase the emphasis on the system
level understanding of wireless, networking, and other communications technologies.
Because of the heavy integration of communications circuits today, the engineer and the
technician now work more with printed circuit boards, modules, plug-in cards, and equip-
ment rather than component level circuits. As a result, older obsolete circuits have been
removed from this text and replaced with more integrated circuits and block diagram level
analysis. Modern communications engineers and technicians work with specii cations and
standards and spend their time testing, measuring, installing, and troubleshooting. This
edition moves in that direction. Detailed circuit analysis is still included in selected areas
where it proves useful in understanding the concepts and issues in current equipment.
In the past, a course in communications was considered an option in many elec-
tronic programs. Today, communications is the largest sector of the electronics i eld
with the most employees and the largest equipment sales annually. In addition, wire-
less, networking, or other communications technologies are now contained in almost
every electronic product. This makes a knowledge and understanding of communica-
tion a must rather than an option for every student. Without at least one course in
communications, the student may graduate with an incomplete view of the products
and systems so common today. This book can provide the background to meet the
needs of such a general course.
As the Communications Editor for Electronic Design Magazine (Penton), I have
observed the continuous changes in the components, circuits, equipment, systems, and
applications of modern communications. As I research the i eld, interview engineers and
executives, and attend the many conferences for the articles and columns I write, I have
come to see the growing importance of communications in all of our lives. I have tried
to bring that perspective to this latest edition where the most recent techniques and
technologies are explained. That perspective coupled with the feedback and insight from
some of you who teach this subject has resulted in a textbook that is better than ever.
New to this Edition
Here is a chapter-by-chapter summary of revisions and additions to this new edition.
Chapters 1–6 Updating of circuits. Removing obsolete circuits and adding current
circuits.
Chapter 7 U pdated section on data conversion, including a new section on overs-
ampling and undersampling.
viii
Chapter 8 Expanded coverage of the I/Q architecture for digital data transmis-
sion. New section on phase noise. Addition of broadband linear
power amplii ers using feedforward and adaptive predistortion tech-
niques. New coverage of Doherty amplii ers and envelope tracking
amplii ers for improved power efi ciency. Addition of new IC trans-
mitters and transceivers. New coverage of LDMOS and GaN RF
power transistors.
Chapter 9 Expanded coverage of receiver sensitivity and signal-to-noise ratio, its
importance and calculation. Addition of AWGN and expanded coverage
of intermodulation distortion. Increased coverage of the software-
dei ned radio (SDR). New IC receiver circuits and transceivers.
Chapter 10 Updated coverage of multiplexing and access techniques.
Chapter 11 Expanded coverage of digital modulation and spectral efi ciency.
Increased coverage of digital modulation schemes. New coverage of
DSL, ADSL, and VDSL. Addition of cable TV system coverage.
Improved coverage of the OSI model. Addition of an explanation of
how different digital modulation schemes affect the bit error rate
(BER) in communications systems. Updated sections on spread spec-
trum and OFDM. A new section on convolutional and turbo coding
and coding gain.
Chapter 12 Heavily revised to emphasize fundamentals and Ethernet. Dated mate-
rial removed. Expanded and updated to include the latest Ethernet stan-
dards for i ber-optic and copper versions for 100 Gbps.
Chapter 13 Minor revisions and updates.
Chapter 14 M inor revisions and updates.
Chapter 15 Fully updated. Addition of coverage of IPv6 and the Optical Transport
Network standard.
Chapter 16 U pdated with new emphasis on millimeter waves. Updated circuitry.
Chapter 17 R evised and updated.
Chapter 18 Removal of dated material and updating.
Chapter 19 E xpanded section on MSA optical transceiver modules, types and
specii cations. OM i ber added. Addition of coverage of 100-Gbps
techniques, including Mach-Zehnder modulators and DP-QPSK
modulation.
Chapter 20 E xtensively revisions on cell phone technologies. New coverage on
HSPA and Long Term Evolution (LTE) 4G systems. Analysis of a
smartphone. Backhaul. A glimpse of 5G including small cells.
Chapter 21 U pdates include addition of the latest 802.11ac and 802.11ad Wi-Fi
standards. New coverage on machine-to-machine (M2M), the Internet
of Things (IoT), and white space technology.
Chapter 22 Revisions and updates include a new section on vector signal analyzers
and generators.
One major change is the elimination of the ineffective chapter summaries. Instead,
new Online Activity sections have been added to give students the opportunity to
further explore new communications techniques, to dig deeper into the theory, and to
become more adept at using the Internet to i nd needed information. These activities
show students the massive stores of communications information they can tap for free
at any time.
In a large book such as this, it’s difi cult to give every one what he or she wants. Some
want more depth, others greater breadth. I tried to strike a balance between the two. As
always, I am always eager to hear from those of you who use the book and welcome your
suggestions for the next edition.
