Wireless telecommunication systems generate a huge amount of interest. In the last two decades, these systems have experienced at least three major technological leaps, and it has become impossible to imagine how society was organized without them. In this book, we propose a macroscopic approach on wireless systems, and aim at answering key questions about power, data rates, multiple access, cellular engineering and access networks architectures. We present a series of solved problems, whose objective is to establish the main elements of a global link budget in several radiocommunications systems. Contents 1. Radio Propagation. 2. F/TDMA and GSM. 3. CDMA and UMTS. 4. OFDM and LTE. 5. MIMO an...
This book, written by leading experts from academia and industry, offers a condensed overview on hot topics among the Cognitive Radios and Networks scientific and industrial communities (including those considered within the framework of the European COST Action IC0902) and presents exciting visions for the future. Examples of the subjects considered include the design of new filter bank-based air interfaces for spectrum sharing, medium access control design protocols, the design of cloud-based radio access networks, an evolutionary vision for the development and deployment of cognitive TCP/IP, and regulations relevant to the development of a spectrum sharing market. The concluding chapter comprises a practical, hands-on tutorial for those interested in developing their own research test beds. By focusing on the most recent advances and future avenues, this book will assist researchers in understanding the current issues and solutions in Cognitive Radios and Networks designs.
The idea of universal rights is often understood as the product of Europe, but as Laurent Dubois demonstrates, it was profoundly shaped by the struggle over slavery and citizenship in the French Caribbean. Dubois examines this Caribbean revolution by focusing on Guadeloupe, where, in the early 1790s, insurgents on the island fought for equality and freedom and formed alliances with besieged Republicans. In 1794, slavery was abolished throughout the French Empire, ushering in a new colonial order in which all people, regardless of race, were entitled to the same rights. But French administrators on the island combined emancipation with new forms of coercion and racial exclusion, even as newly...
Encompassing the work of historians, art-historians, and literary scholars, these essays explore how interrelated processes of communal inclusion and exclusion - articulated through institutions, discourses, performances, and artefacts - shaped the construction of individual and collective identities in medieval Europe.
