The very title of this book is borrowed from the information theory vocabulary, and, quite naturally, it is an outline of this theory that will serve as an introduction. The subject of information theory is the scientific study of communicaTIONs. To this end it defines a quantitative measurement of the communicated content, i.e. informa- tion, and deals with two operations essential for communicaTION techniques: source coding and channel encoding.

Employing multiple transmit and receive antennas, namely using multi-input multi-output (MIMO) systems, has proven to be a major breakthrough in providing reliable wireless communicaTION links. Since their invention in the mid-1990s, transmit diversity, achieved through space-time coding, and spatial multiplexing schemes have been the focus of much research in the area of wireless communicaTIONs.

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.

communicaTION today is not as easy as it was in the past. Protecting numerous com- munication services, which are operating in the same or adjacent communicaTION channels, has become increasingly challenging. communicaTION systems have to be protected from both natural and manmade interference. Electromagnetic interfer- ence can be radiated or conducted, intentional or unintentional.

During the past decade, many wireless communicaTION techniques have been developedto achievevariousgoals suchas higherdata rate,morerobustlink quality, and higher number of users in a given bandwidth. For wireless communicaTION systems, depending on the availability of a feedback link, two approaches can be considered: namely open and closed loop. Open loop communicaTION system that does not exploit the channel knowledge at the transmitter is now well understood from both a theoretical and practical point of view.

Free Space Optical communicaTION (FSOC) is an effective alternative technology to meet the Next Generation Network (NGN) demands as well as highly secured (mili- tary) communicaTIONs. FSOC includes various advantages like last mile access, easy installation, free of Electro Magnetic Interference (EMI)/Electro Magnetic Compatibil- ity (EMC) and license free access etc. In FSOC, the optical beam propagation in the turbulentatmosphereisseverelyaffectedbyvariousfactorssuspendedinthechannel, geographicallocationoftheinstallationsite,terraintypeandmeteorologicalchanges. Therefore a rigorous experimental study over a longer period becomes significant to analyze the quality and reliability of the FSOC channel and the maximum data rate that the system can operate since data transmission is completely season dependent.
