Digital Terrestrial Broadcasting Networks approachs the existing framework for digital terrrestrial broadcasting, particularly the results of the Regional Radiocommunication Conference held in 2006. That conference established a new frequency plan for Europe, Africa and parts of Asia for digital terrestrial broadcasting. The book introduces the currently existing terrestrial broadcasting systems as well as the regulatory framework by which they can begin operating. Most importantly the book explains details of the GE06 Agreement, particularly Articles 4 and 5. It also discusses the frequency plan itself and the constraints it has been derived under. The book addresses the implementation of the GE06 Plan, which leads directly to all issues related to network planning and optimization of networks. Finally, the future development of the Plan and the digital dividend is addressed. This covers issues like sharing the UHF spectrum with mobile communication services and also touches upon the World Radio Conference 07 to be held in the fall in Geneva.

Additional explanations of the standard and especially the test cases will help to better understand the effects on any front-end system design. Many references are provided for readers interested in in-depth treatments of certain topics.

This book constitutes the Final Report of COST Action 279, Analysis and DesignofAdvancedMultiserviceNetworkssupportingMultimedia, Mobility, andInterworking, a guided tour of the state-of-the-art work on diverse aspects of modern telecommunications networks design developed within this Action during the four years of its operation, started on July 1, 2001, and ended on June 30, 2005. As stated in its founding charter, its Memorandum of Understanding, the work area of COST 279 is the analysis, design, and control aspects of prese- day networks-quite a wide scope. Behind the unifying fac, ade put on by the Internet Protocol (IP) network layer, todays networks hide a mess of hete- geneity: heterogeneity at the level of applications, both concerning the traf?c they produce and the network Quality of Service (QoS) they require, and h- erogeneity at the level of network component subsystems, in particular an - creasingly important mobile/wireless access segment. A common ground for the treatment of this disparate set of topics was given by the strong meth- ological component contained in the approach followed in COST 279, with importance placed on the development and application, whenever possible, of analytical techniques and models for the mathematical understanding of the systems under study. The results expected from the Action ranged thus from mathematical models and algorithms as entities of own interest to the und- standing of systembehavior via their application."

Since the advent of optical communications, a greattechnological effort has been devoted to the exploitation of the huge bandwidth of optical fibers. Sta- ing from a few Mb/s single channel systems, a fast and constant technological development has led to the actual 10 Gb/s per channel dense wavelength - vision multiplexing (DWDM) systems, with dozens of channels on a single fiber. Transmitters and receivers are now ready for 40 Gb/s, whereas hundreds of channels can be simultaneously amplified by optical amplifiers. Nevertheless, despite such a pace in technological progress, optical c- munications are still in a primitive stage if compared, for instance, to radio communications: the widely spread on-off keying (OOK) modulation format is equivalent to the rough amplitude modulation (AM) format, whereas the DWDM technique is nothing more than the optical version of the frequency - vision multiplexing (FDM) technique. Moreover, adaptive equalization, ch- nel coding or maximum likelihood detection are still considered something "exotic" in the optical world. This is mainly due to the favourable char- teristics of the fiber optic channel (large bandwidth, low attenuation, channel stability, ...), which so far allowed us to use very simple transmission and detection techniques.

Optical networks have been in commercial deployment since the early 1980s as a result of advances in optical, photonic, and material technologies. Although the initial deployment was based on silica ?ber with a single wavelength modulated at low data rates, it was quickly demonstrated that ?ber can deliver much more bandwidth than any other transmission medium, twisted pair wire, coaxial cable, or wireless. Since then, the optical network evolved to include more exciting technologies, gratings, optical ?lters, optical multiplexers, and optical ampli?ers so that today a single ?ber can transport an unprecedented aggregate data rate that exceeds Tbps, and this is not the upper limit yet. Thus, the ?ber optic network has been the network of choice, and it is expected to remain so for many generationsto come, for both synchronousand asynchronouspayloads; voice, data, video, interactive video, games, music, text, and more. In the last few years, we have also witnessed an increase in network attacks as a result of store andforwardcomputer-basednodes. These attackshave manymaliciousobjectives: harvestsomeone else's data, impersonate another user, cause denial of service, destroy ?les, and more. As a result, a new ?eld in communicationis becomingimportant, communicationnetworksand informationse- rity. In fact, the network architect and system designer is currently challenged to include enhanced features such as intruder detection, service restoration and countermeasures, intruder avoidance, and so on. In all, the next generation optical network is intelligent and able to detect and outsmart malicious intruders.

Fundamentals of Optical Fiber Sensor Technology The field of optical fiber sensors continues to expand and develop, being increasingly influenced by new applications of the technologies that have been the topics of research for some years. In this way, the subject continues to mature and reach into new areas of engineering. This text in the series on Optical Fiber Sensor Technology provides a foundation for a better understanding of those developments in the basic science and its applications in fiber sensors, underpinning the subject today. This book builds upon the work in an earlier single volume which covered a broad area of the subject, but which now, in this, volume 1 of the series, focuses upon the fundamentals and essentials of the technology. Material which is included has been carefully reviewed and in most cases thoroughly revised and expanded to reflect the current state of the subject, and provide an essential background for the more applications-oriented content of the subsequent volumes of the series. This volume opens with a status paper on optical fiber sensor technology, by Kenneth Grattan and Tong Sun providing in it a flavor of the main topics in the field and giving an essential overview at the sort of systems which are discussed in more detail in the other chapters in the whole series. An extensive publication list of readily accessible papers reflecting these topics is included.

Feedforward Amplifiers for Wideband Communication Systems has been possible thanks to the research carried out throughout several years in the field of the linearization techniques applied to digital communication systems, particularly to those with high spectral efficient modulation techniques.

The wireless telecommunications are more and more demanded for the Information Society. Such requirements are reflected as a great many of communication standards with specific coverage applications and, above all, with higher and higher data transmission rates.

The electromagnetic spectrum, nevertheless, is a scarce asset that can not be spread and despite the increasingly tendency to transmit in higher frequencies, the bandwidths assigned to each application are always exploited to the limit.

Feedforward Amplifiers for Wideband Communication Systems merges in the need of developing frequency efficient modulations with widespread codification techniques that result in wideband communication systems, with strict regulations in the usable frequency bandwidths and tight restrictions in the spurious emissions over the remaining spectrum.

The radio frequency transmitters do not remain impassive to those changes, especially the power amplifiers, which efficiency and linearity directly determines the correct performance of the entire transmission system. The linearity specifications are commonly fixed by the telecommunication standards while the efficiency rates directly strikes the commercial viability of these transmitters.

Feedforward Amplifiers for Wideband Communication Systems tries to put into practice the Feedforward linearization technique, aimed at improving either the linearity or efficiency parameters of power amplifiers, just intended for achieving a trade-off between the distortion specifications of the telecommunication standards and the efficiency enhancement of the transmission systems, which set, respectively, the linearity and the output level requirements of power amplifiers.

This challenge is enshrined in one of the present wideband communication systems, but all the recommended design guidelines are perfectly reusable in the future wideband applications.
