Description: Abstract cognitive radio can automatically sense the external environment and the wireless system parameters can be adjusted to adapt to environmental changes. Perception of the radio frequency spectrum detection is one of the key, requiring the user perceived reliability, rapid detection of spectrum holes. The article according to the main transmitter detects the user and primary user detection receiver, the main spectrum of the current detection algorithms for classification, and spectral detection algorithms are discussed and compared, and the spectrum is given in IEEES02.22 pool structure spectral detection of the specific application.
