Foreword by the editors: DSL’s worldwide coronation of broadband Internet service motivates this comprehensive and timely encyclopedia of DSL transmission fundamentals. Rising star, author, and editor Philip Golden joins industry veterans Herve Dedieu and Krista S. Jacobsen to collect an ´ outstanding set of expert contributors who press the advances of DSL in two volumes — this one and the upcoming Implementation and Applications of xDSL Technology — detailing all aspects of DSL modem design. Readers and students of these volumes indeed hold the keys to all aspects of DSL design in their library. One envisions designers and students around the world depending on the enormous information within. This first volume lays a foundation, addressing the basics of DSL.
There have been many texts on DSL in the past few years, including the heavily referenced two-book set by Starr, Sorbara, Cioffi, and Silverman  , Walter Chen’s earliest text , John Bingham’s final classic  before retiring, and Dennis Rauschmayer’s pragmatic view . However, none has been as comprehensive as this ambitious collection’s realization. The DSL area has been expanding rapidly, making an address by a single author or small group of authors difficult. This text addresses the overall need by combining the strengths of the world’s most renowned DSL experts.
A good transmission engineer’s first rule is “know your channel,” and this text reinforces that notion: a caboodle of Europe’s finest DSL engineers adorns an introductory threechapter examination of DSL copper transmission channels in this first volume. Golden, an internationally acknowledged expert on splitter circuits, joins DSL’s premier analog expert, BT engineer John Cook, to overview the basic telephone environment in the first chapter. Fundamentally, strong transmission in DSL depends on a good understanding of the physical-layer twisted pair, provided in Chapter 2 by renowned analog expert Herve´ Dedieu. Such good transmission depends also on good noise models, which are provided in the third chapter by another BT expert, Rob Kirkby.
Modulation and equalization expert Ragnar Jonsson of Conexant introduces all line codes in Chapter 4, to set up later chapters that provide greater depth in and understanding of the various transmission methods. Professor Edward Jones of University College Galway, Ireland, relates in Chapter 5 the materialization of the basic objectives in DSL service and compares DSL to other methods of broadband delivery.
Seven succeeding chapters describe the basics of DSL transmission to complete this first volume. The “transmission fest” begins in Chapter 6, which provides an excellent review of single-carrier modulation by highly mobile author Vladimir Oksman of Tadiran, Lucent, Broadcom, and currently Infineon. A professor could not be more proud than to see the fine work in this volume by two former outstanding students, the first of whom is Krista S. Jacobsen, formerly of Texas Instruments, internationally recognized for her exceptional understanding of the discrete multi-tone (DMT) technology. Her Chapter 7 provides a comprehensive treatment of DMT transmission methods that should allow many to understand this simple but high-performing ubiquitous DSL technique, which, following its selection for both ADSL and VDSL, has clearly become the industry favorite. Krista is followed by Broadcom’s coding-world superstar Gottfried Ungerboeck, who details his internationally acclaimed trellis codes for DSL in Chapter 8. A second former student, Texas Instruments’ frame-format and coding pioneer Cory Modlin, then follows in Chapter 9 with a detailed investigation of the Reed–Solomon codes and interleaving used in almost all DSL systems. Turbo and LDPC codes may find their way into use in DSL’s future, and IBM Zurich Research Lab’s Evangelos Eleftheriou and Sedat Ol ¨ cer are the premier experts on ¸ the possibilities, which appear in Chapter 10. Iceland’s Ragnar Jonsson returns in Chapter 11 to review basic equalization theory for use in DSL.
Initially noted but under-appreciated, radio-frequency (RF) interference is a major source of performance loss at high speeds in some DSLs. A quartet of Swedish–Bavarian authors — Rickard Nilsson, Thomas Magesacher, Steffen Trautmann, and Tomas Nordstrom¨ — provide a valuable investigation of RF issues and means for reducing or suppressing RF interference in DSL.
Having completed this first basic volume, excitement builds in anticipation of the ensuing volume that addresses the methods for expansion and growth of DSL’s success.
