Software-defined radio (SDR) is the hottest area of RF/wireless design, and this title describes SDR concepts, theory, and design principles from the perspective of the signal processing (both on transmission and reception) performed by a SDR system. After an introductory overview of essential SDR concepts, this book examines waveform creation, analog signal processing, digital signal processing, data conversion, phase-locked loops, SDR algorithms, and SDR hardware design. The various trade-offs at each of these design stages are discussed in detail.*Offers readers a powerful set of an

Reconfigurable RF-frontends aim to cope with the continuous pursuit of wider frequency coverage, higher efficiency, further compactness and lower cost of ownership. They are expected to lay the foundations of future software defined or cognitive radios. As a potential enabling technology for the frontends, the tunable ferroelectric devices have shown not only enhanced performance but also new functionalities. This book explores the recent developments in the field. It provides a cross-sectional perspective on the interdisciplinary research. With attention to the devices based on ceramic thick-films and crystal thin-films, the book reviews the adapted technologies of material synthesis, film deposition and multilayer circuitry. Next, it highlights the original classes of thin-film ferroelectric devices, including stratified metal-insulator-metal varactors with suppression of acoustic resonance and programmable bi-stable high frequency capacitors. At the end the book analyzes how the frontends can be reformed by tunable multiband antennas, tunable single- and multiband impedance matching networks and tunable substrate integrated waveguide filters, which are all built on low cost ferroelectric thick-films. For all the above devices, the theoretical analyses, modeling and design methods are elaborated, while through demonstrative prototypes the application potential is evaluated.

Mobile users need a variety of multimedia services, in very diverse geographical environments. The growing number of communication options within and across wireless standards is accommodating the growing volume and heterogeneity in wireless demands. On the other hand, advancement in radio technologies opening much more flexibility, a.o. through Software Defined Radios, opens up the possibility to realize mobile devices featuring multi-mode options at low cost and interesting form factors. It is crucial to manage the new degrees of freedom opened up in radios and standards in a smart way, such that the required service is offered at satisfactory quality, as efficiently as possible. Efficiency in energy consumption is paramount for battery powered mobile terminals, as well as in a broader, ecological context. Moreover, efficient usage of the spectrum is a growing prerequisite for wireless systems, and coexistence of different standards puts overall throughput at risk. The management of flexibility risks entails complexity which hampers the desired system agility. This book describes a systematic approach to master this challenge. Case studies show that this approach enables smart operation of radios realizing impressive efficiency gains, without hampering Quality-of-Service. Provides a concise overview of software defined radio technologies, opportunistic spectrum access and wireless standards; introduces opportunities and challenges related to the smart operation of radios in this context. Proposes a systematic approach to master the complexity of the desired agility. Demonstrates the application and benefits of this approach in recent systems, e.g. in WiFi context, and in the context of coexistence of different systems. Shows the need and potential in future scenarios, where cognitive radios will operate in an open spectrum environment.
