WIRELESS communications and networking technology are advancing at a very rapid pace. Newer technologies and standards are evolving to serve the ever-increasing num- ber of users demanding different types of mobile applications and services. Research and development activities on WIRELESS technology constitute one of the most impor- tant segments of research and development in the telecommunications area today.

An understanding of the policies, regulations, standards and techniques of radio spectrum management is useful to those who manage and administrate it, to operators, to equipment providers and to the users of WIRELESS communication (i.e., all of us). For many years the author has been deeply involved in ruling the RF spectrum at the national, regional and global levels. The book is based on the professional experience of the author, his academic courses, presenta- tions and tutorials in five continents. The book reflects this legacy and will be of use to engineers, lawyers and economists, who serve the global industry of the WIRELESS world; in it they may find solutions to the problems they frequently encounter.

Digital mobile WIRELESS communication and the Internet have undergone a fantastic growth in the last few years and, despite originating from two different worlds, they are converging. This convergence corresponds to the evolution of mobile systems towards the highest broadband data transmissions (GSM, EDGE/GPRS, UMTS then HSDPA), while the computing world gets equipped with WIRELESS technologies such as Wi-Fi or Wi-Max.

Mobile and WIRELESS communication systems are a prominent communications technology of the twenty-first century with profound economic and social impacts in practically all parts of the world. The current state of WIRELESS communication systems allows for a much wider scope of applications than what it used to be originally, that is, to be a mobile extension of the public switched telephone network.

The unguided transmission of information using electromagnetic waves at radio frequency (RF) is often referred to as WIRELESS communications, the first demonstration of which took place at the end of the 19th cen- tury and is attributed to Hertz. The technology was, shortly thereafter, commercialised by, amongst others, Marconi in one of the first wire- less communication systems, i.e., WIRELESS telegraphy. In the first half of the 20th century the technology was developed further to enable more than the mere transmission of Morse code. This first resulted in uni- directional radio broadcasting and several years later also in television broadcasting.

The market for cellular phones and WIRELESS data transmission equipment has changed dramatically since the late 1970s when cellular phones were first introduced and the late 1980s when WIRELESS data equipment became available. As would be expected, duringthistime RF test requirements and RF test equipment has changed dramatically.

The multiple-input multiple-output (MIMO) technique provides higher bit rates and better reliability in WIRELESS systems. The efficient design of RF transceivers has a vital impact on the implementation of this technique. This first book is com- pletely devoted to RF transceiver design for MIMO communications. The book covers the most recent research in practical design and applications and can be an important resource for graduate students, WIRELESS designers, and practical engineers.

Cognitive radios have become a vital solution that allows sharing of the scarce frequency spectrum available for WIRELESS systems. It has been demonstrated that it can be used for future WIRELESS systems as well as integrated into 4G/5G WIRELESS systems. Although there is a great amount of literature in the design of cognitive radios from a system and networking point of view, there has been very limited available literature detailing the circuit implementation of such systems. Our textbook, Radio Frequency Integrated Circuit Design for Cognitive Radios, is the first book to fill a disconnect in the literature between Cognitive Radio systems and a detailed account of the circuit implementation and architectures required to implement such systems. In addition, this book describes several novel concepts that advance state-of-the-art cognitive radio systems.

With the advent of IMT-2000, CDMA has emerged at the focal point of interest in WIRELESS communications. Now it has become impossible to discuss WIRELESS communications without knowing the CDMA technologies. There are a number of books readily published on the CDMA technologies, but they are mostly dealing with the traditional spread-spectrum technologies and the IS-95 based CDMA systems. As a large number of novel and interesting technologies have been newly developed throughout the IMT-2000 standardization process in very recent years, new reference books are now demanding that address the diverse spectrum of the new CDMA technologies.

This book was born from the perception that there is much more to spectrum use and sharing than one sees reflected in publications, whether academic, commercial or political. the former – in good research style – tend towards reductionism and concentrate on specific, detailed aspects. commercial publications tend to empha- size the positive aspects and they tend to put promise above practice. Given the ever increasing pace of technology development and recent successes of new WIRELESS technologies, some pundits predict large-scale spectrum scarcity, potentially lead- ing to economic catastrophe. Although economic theory has a hard time explaining recent events that shook the world economy, the notion of spectrum scarcity is intui- tively acceptable, even if not correct or immediately relevant.
