Spectrum Sensing Techniques And Applications [Paperback]

Cognitive radio, the technology of transmitting radio communications by having a receiver that can detect used, versus unused, signal channels, is increasingly important with the ever expanding use of wireless communications. The central principle for this enabling technology is spectrum sensing, the ability for a receiver to recognize how channels it identifies are being used at any given point in time and space, and then adjust the communications of a device accordingly to make the most efficient use of available channels. This new book will cover the latest developments in spectrum sensing, as well as the underlying technical principles involved including statistical formulation and the fundamental concepts of signal detection. It will go on to show how spectrum sensing is used in cognitive radio and dynamic spectrum access. This book will fill in the gaps from current books, and offer the reader an interesting, robust and illustrative treatment, with recent practical applications of cognitive radio and spectrum sensing.
