The BBC is one of the most important institutions in Britain; it is also one of the most misunderstood. Despite its claim to be independent and impartial, and the constant accusations of a liberal bias, from its Reithian origins to its coverage of the 2019 General Election: the BBC has always sided with the elite. As Tom Mills demonstrates, we are only getting the news that the Establishment wants aired in public. And yet in the current age of multi-platform news, this bias is increasingly exposed. Mills asks if the institution is fit for purpose? And can it even be reformed? The BBC is an important and timely examination of a crucial public institution that may threaten the very thing it was meant to uphold: democracy.

John Joseph Fahie (1846 1934) was an engineer for the Electric and International Telegraph Company before being posted overseas in the Indo-European Government Telegraph Department. He was also a respected historian whose History of Wireless Telegraphy (1899) sold out two impressions in little over a year. In this second edition (1901), he traces the development of wireless communication during the nineteenth century, drawing extensively from the correspondence and technical illustrations of inventors themselves. This edition was fully updated to take account of the latest advances in radio technology, including Marconi's latest public demonstrations. As a practising telegraph engineer, Fahie was in the perfect position not only to understand the significance of these developments, but to explain them to a non-specialist audience. Contemporary reviews indicate he did this with great success. His book gives an eyewitness account of the rise of radio technology that still fascinates scholars and enthusiasts today.

An exciting new technology, described by the one who invented it

This is the first book dedicated to cognitive radio, a promising new technology that is poised to revolutionize the telecommunications industry with increased wireless flexibility. Cognitive radio technology integrates computational intelligence into software-defined radio for embedded intelligent agents that adapt to RF environments and user needs. Using this technology, users can more fully exploit the radio spectrum and services available from wireless connectivity. For example, an attempt to send a 10MB e-mail in a zone where carrier charges are high might cause a cognitive radio to alert its user and suggest waiting until getting to the office to use the LAN instead. Cognitive Radio Architecture examines an "ideal cognitive radio" that features autonomous machine learning, computer vision, and spoken or written language perception.

The author of this exciting new book is the inventor of the technology and a leader in the field. Following his step-by-step introduction, readers can start building aware/adaptive radios and then make steps towards cognitive radio. After an introduction to adaptive, aware, and cognitive radio, the author develops three major themes in three sections: FoundationsRadio CompetenceUser Domain Competence

The book makes the design principles of cognitive radio more accessible to students of teleinformatics, as well as to wireless communications systems developers. It therefore embraces the practice of cognitive radio as well as the theory. In particular, the publication develops a cognitive architecture that integrates disparate disciplines, including autonomous machine learning, computer vision, and language perception technologies. An accompanying CD-ROM contains the Java source code and compiled class files for applications developed in the book. In addition, for the convenience of the reader, Web resources introducing key concepts such as speech applications programmer interfaces (APIs) are included.

Although still five to ten years away from full deployment, telecommunications giants and research labs around the world are already dedicating R&D to this new technology. Telecommunications engineers as well as advanced undergraduate and graduate students can learn the promising possibilities of this innovative technology from the one who invented it.

Note: CD-ROM/DVD and other supplementary materials are not included as part of eBook file.
