During the past two decades, technological development Related to telecommuni- cation technologies has allowed organizations of all types and size to be able to de- velop effective networking applications in support of information management. Fur- thermore, telecommunication technologies combined with computer technology have created the foundation of modern information technology which has affected all as- pects of societal and organizational functions in our modern world.

This work titled A Digital Phase Locked Loop based Signal and Symbol Recovery System for Wireless Channel is intended to serve as a document covering funda- mental concepts and application details Related to the design of digital phase locked loop (DPLL) and its importance in wireless communication. It documents some of the work done during the last few years covering rudimentary design issues, complex implementations, and fixing configuration for a range of wireless propa- gation conditions.

Following chapter introduces the mobile communication, gives a short history of wireless communication evolution, and highlights some application scenarios predestined for the use of mobile devices. Cellular and wireless based systems Related to different generations of mobile communication, including GSM, IS-95, PHS, AMPS, D-AMPS, cdma2000 and WCDMA are also described by this Chapter. Much attention in this chapter is given to express the wireless based networks, such as Wi-Fi and WiBro/WiMax, and wireless broadcasting systems, including DMB, DVB-H, and ISDB-T. We conclude the chapter with the future vision of mobile communication evolution

The wireless market has experienced a phenomenal growth since the first second- generation (2G) digital cellular networks, based on global system for mobile communications (GSM) technology, were introduced in the early 1990s. Since then, GSM has become the dominant global 2G radio access standard. Almost 80% of today’s new subscriptions take place in one of the more than 460 cellular networks that use GSM technology. This growth has taken place simultaneously with the large experienced expansion of access to the Internet and its Related multimedia services.

This book was conceived in such a special way. From our experience, and despite the increasing interest that we perceived amongst the research community in HAPS, there was not any book in the market entirely devoted to HAPS. We could only find some satellite communications books including only fragments Related to HAPS, covering the ‘generalities’. A need for a reference book which could highlight state- of-the-art HAPS-Related topics was therefore envisaged. Moreover, most of the information Related to HAPS could only be found in technical reports, official recommendations, conference proceedings and journal papers.

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.

In general there are three different techniques for performance evaluation of systems and networks: mathematical analysis, measurements, and computer simulation. All these techniques have their strength and weaknesses. In the literature there are plenty of discussions about when to use which technique, how to apply it, and which pitfalls are Related to which evaluation technique.

At recent major international conferences on wireless communications, there have been several sessions on beyond third generation (3G) or fourth generation(4G)mobilecommunicationssystems,wheremodulation/demod- ulation and multiplexing/multiple access schemes Related to multicarrier techniques have drawn a lot of attention. We often met at the conference venuesandrealizedthatnobookcoveredthebasicsofmulticarriertechniques to recent applications aiming at the 4G systems. Therefore, we decided to write a book on multicarrier techniques for 4G mobile communications systems.
