Description: Spectrum sensing is critically important for cognitive radio, an emerging solution
to the spectrum congestion and low usage of licensed spectrum. Energy detection
is a promising low-complexity and low-cost spectrum sensing technique. Its
performance analysis has been revisited extensively in the recent literature. This
book thus aims at a comprehensive summary of recent research on energy detection
for spectrum sensing in cognitive radio networks. This book is for researchers
and engineers in both industry and academia who would like to know more about
applications of energy detection.
