This book has grown out of my teaching and research at the University of Surrey and out of my previous experiences in companies such as Philips, Ascom and Motorola. It is primarily intended for use by students in master’s level and enhanced final-year under- graduate courses who are specialising in communication systems and wish to understand the principles and current practices of the wireless communication channel, including both ANTENNA and propagation aspects

When we started thinking about writing the first edition of this book a few years ago, we had been working together for more than five years on the borderline between propagation and signal processing. Therefore, it is not surprising that this book deals with propagation models and design tools for MIMO wireless communications. Yet, this book should constitute more than a simple combination of these two domains. It hopefully conveys our integrated understanding of MIMO, which results from endless controversial discussions on various multi-ANTENNA related issues, as well as various interactions with numerous colleagues. Obviously, this area of technology is so large that it is beyond our aim to cover all aspects in details. Rather, our goal is to provide researchers, R&D engineers and graduate students with a comprehensive coverage of radio propagation models and space–time signal processing techniques for multi-ANTENNA, multi-user and multi-cell networks.

Due to the asymmetry between the amount of data traffic in the downlink and uplink direction of nowadays and future wireless networks, a proper design of the transceivers in the broadcast channel is inevitable in order to satisfy the users’ demands on data rate and transmission quality. This book deals with the optimi- zation-based joint design of the transmit and receive filters in a MIMO broadcast channel in which the user terminals may be equipped with several ANTENNA ele- ments.

Use of multiple ANTENNAs at both ends of wireless links is the result of the natural progression of more than four decades of evolution of adaptive ANTENNA technology. Recent advances have demonstrated that multiple- input-multiple-output (MIMO) wireless systems can achieve impressive increases in overall system performance.

An acronym for Multiple-In, Multiple-Out, MIMO communication sends the same data as several signals simultaneously through multiple ANTENNAs, while still utilizing a single radio channel. This is a form of ANTENNA diversity, which uses multiple ANTENNAs to improve signal quality and strength of an RF link. The data is split into multiple data streams at the transmission point and recombined on the receive side by another MIMO radio configured with the same number of ANTENNAs. The receiver is designed to take into account the slight time difference between receptions of each signal, any additional noise or interference, and even lost signals.

The explosion in demand for wireless services experienced over the past 20 years has put significant pressure on system designers to increase the capacity of the systems being deployed. While the spectral resource is very scarce and practically exhausted, the biggest possibilities are predicted to be in the areas of spectral reuse by unlicensed users or in exploiting the spatial dimension of the wireless channels. The former approach is now under intense development and is known as the cogni- tive radio approach (Haykin 2005).

In modern societies, the production and trade of goods all around the world is constantly increasing. The latest technological achievements allow the mass-production of millions of items of every kind, which are being exchanged all around the globe with unprecedented rapidity. At the same time, the problem of identifying, classifying and tracking such a growing multitude of objects is con- sequently arising.

We are in the era of ubiquitous computing in which the use and development of Radio Frequency Iden- tification (RFID) is becoming more widespread. RFID systems have three main components: readers, tags, and database. An RFID tag is composed of a small microchip, limited logical functionality, and an ANTENNA. Most common tags are passive and harvest energy from a nearby RFID reader. This energy is used both to energize the chip and send the answer back to the reader request. The tag provides a unique identifier (or an anonymized version of that), which allows the unequivocal identification of the tag holder (i.e. person, animal, or items).

If one examines the current literature on GPS receiver design, most of it is quite a bit above the level of the novice. It is taken for granted that the reader is already at a fairly high level of understanding and proceeds from there. This text will be an attempt to take the reader through the concepts and circuits needed to be able to understand how a GPS receiver works from the ANTENNA to the solution of user position.
