The increasing need for functional flexibility (the number of wireless standards is large and expected to grow) and the exploding cost of system-on-chip design will make implementation of wireless standards on reconfigurable radios the only viable option in the future. Software Defined Radios (SDRs) will offer higher flexibility at lower cost. Moreover, they are key enablers in the realization of cognitive radios, which will enable more efficient use of network and spectral resources.Green SDRs will be essential, to save on crucial and scarce resources: energy and spectrum. Green Software Defined Radios gives insight in the trends asking for green SDRs. The essential ingredients of these radios are elaborated on. Specifically, design solutions and approaches for energy-scalable SDRs, both for the radio front-end and the digital baseband (including hardware and software), are explained. Intelligent (cross-layer) control is introduced as the key to achieve energy efficient operation and seamless connectivity. Last but not least the book focuses on cognitive radios, opening a new wireless order. These radios build on SDR platforms, enhanced with a sensing engine and intelligent control.

This book explores the design of ultra-low-power radio-frequency integrated circuits (RFICs), with communication distances ranging from a few centimeters to a few meters. The authors describe leading-edge techniques to achieve ultra-low-power communication over short-range links. Many different applications are covered, ranging from body-area networks to transcutaneous implant communications and smart-appliance sensor networks. Various design techniques are explained to facilitate each of these applications.
