PREFACE
The proliferation of telecommunications systems and services over the past couple of
decades has been accompanied by numerous advances in physical layer communications
and associated signal processing techniques. Many of these services have
in fact been enabled by the increase in spectral efficiency provided by improved
modulation, coding, and reception capability. Furthermore, the evolution of communications
networks continues to stimulate efforts to push the performance and reliability
of these networks to their fundamental limits.
For the most part, many of the recent advances in signal processing methods for
communications have been motivated by the evolution of mobile cellular systems,
i.e., from first-generation Analog systems, introduced in the 1980s, to next (fourth)-
generation systems currently being designed. Additionalmotivation has been provided
by other wireless systems and standards, such as wireless local and metropolitan area
networks, and also the desire to provide broadband services over existing copper
subscriber lines in the telephone network. Although wired channels, such as subscriber
lines, do not experience the time variations in received signal strength associated
with mobile cellular channels, other challenges remain, such as overcoming
frequency-selectivity and efficient spectrum sharing among multiple users with different
channel characteristics.
This book reviews recent advances in multiuser detection, which generally refers to
methods for detecting digital data associated with multiple interfering signals. These
advances comprise some of the signal processing techniques just mentioned, and have
been an active area of research and development over the past couple of decades. In the
title of this book, “recent” generally refers to advances made over the past ten years,
i.e., since the publication of the first book on multiuser detection [87]. Except for
the first chapter, which gives a general introduction and overview, each of the eight
chapters is contributed by a different set of authors, and is meant to be a self-contained
discussion of a particular topic. Namely, Chapter 2 discusses iterative techniques for
combined multiuser detection and decoding of error control codes; Chapter 3 dicusses
multiuser detection in the presence of linear channel impairments, such multipath and
intersymbol interference; Chapters 4 and 5 present performance analysis of multiuser
detection methods with random signatures and channels; Chapter 6 discusses
the application of joint detection methods to Multi-Input/Multi-Output (MIMO)
channels, corresponding to wireless links with multiple antennas at the transmitter
xv
and/or receiver; Chapter 7 discusses interference avoidance methods at the transmitter
(i.e., through the choice of signatures assuming spread spectrum signaling); and
Chapter 8 discusses transmitter precoding methods for the MIMO downlink
(broadcast channel). A more detailed overview of the chapters is given at the end of
Chapter 1.
These topics represent a sampling of major advances that have been made in multiuser
detection over the past ten years. Because this research area has been quite active,
comprehensive coverage of recent progress would be quite difficult. This book therefore
serves as an entry point for exploring ongoing research in multiuser detection and
for learning about existing unsolved problems and issues. The intended audience is
therefore graduate students in communications, as well as practicing engineers and
researchers who are familiar with digital communications at the level of [87] and
[60], and wish to gain a deeper understanding of multiuser detection techniques.
This area continues to progress and it is our hope that these contributions will stimulate
further advances.
