The field of digital communicaTION has evolved rapidly in the past few decades, with commercial applications proliferating in wireline communi- cation networks (e.g., digital subscriber loop, cable, fiber optics), wireless communicaTION (e.g., cell phones and wireless local area networks), and stor- age media (e.g., compact discs, hard drives). The typical undergraduate and graduate student is drawn to the field because of these applications, but is often intimidated by the mathematical background necessary to understand communicaTION theory.

The writing of this book was prompted by two main developments in wireless communicaTIONs in the past decade. First is the huge surge of research activities in physical-layer wireless communicaTION theory. While this has been a subject of study since the 60’s, recent developments in the field, such as opportunistic and multi-input multi-output (MIMO) communicaTION techniques, have brought completely new per- spectives on how to communicate over wireless channels.

The genesis for this book was my involvement with the development of the SystemView (now SystemVue) simulation program at Elanix, Inc. Over several years of development, technical support, and seminars, several issues kept recur- ring. One common question was, “How do you simulate (such and such)?” The sec- ond set of issues was based on modern communicaTION systems, and why particular developers did what they did. This book is an attempt to gather these issues into a single comprehensive source.

This book presents millimeter wave communicaTION system design and analysis at the level to produce an understanding of the interaction between a wireless system and its front end so that the overall performance can be predicted. Gigabit wireless commu- nications require a considerable amount of bandwidth, which can be supported by millimeter waves. Millimeter wave technology has come of age, and at the time of writing the standards of IEEE 802.15.3c, WiGig, Wireless HD TM , and the European Computer Manufacturers Association have recently been finalized.

This book is about multipoint cooperative communicaTION, a key technology to overcome the long-standing problem of limited transmission rate caused by inter- point interference. However, the multipoint cooperative communicaTION is not an isolated technology. Instead, it covers a vast range of research areas such as the multiple-input multiple-outputsystem, the relay network, channel state information issues, inter-point radio resource management operations, coordinated or joint transmissions, etc. We suppose that any attempt trying to thoroughly analyze the multipoint cooperative communicaTION technology might end up working on a cyclopedia for modern communicaTION systems and easily get lost in discussing all kinds of cooperative communicaTION schemes as well as the associated models and their variations.

Optical wireless communicaTION is an emerging and dynamic research and development area that has generated a vast number of interesting solutions to very complicated communicaTION challenges. For example, high data rate, high capacity and minimum interference links for short-range communicaTION for inter-building communicaTION, computer-to-computer communicaTION, or sensor networks. At the opposite extreme is a long-range link in the order of millions of kilometers in the new mission to Mars and other solar system planets.

This book is a result of the recent rapid advances in two related technologies: com- munications and computers. Over the past few decades, communicaTION systems have increased in complexity to the point where system design and performance analysis can no longer be conducted without a significant level of computer sup- port. Many of the communicaTION systems of fifty years ago were either power or noise limited. A significant degrading effect in many of these systems was thermal noise, which was modeled using the additive Gaussian noise channel.

communicaTION has been one of the deepest needs of the human race throughout recorded history. It is essential to forming social unions, to educating the young, and to expressing a myriad of emotions and needs. Good communicaTION is central to a civilized society. The various communicaTION disciplines in engineering have the purpose of providing technological aids to human communicaTION. One could view the smoke signals and drum rolls of primitive societies as being technological aids to communicaTION, but communicaTION technology as we view it today became important with telegraphy, then telephony, then video, then computer communicaTION, and today the amazing mixture of all of these in inexpensive, small portable devices.
