There are several spectrum sensing techniques that were proposed for CR. A few completely blind sensing methods that does not consider any prior knowledge about the transmitted signal have been derived in the literature, but all of them suffer from the noise uncertainty and fading channels variations. One of the most popular is the energy detector (ED) [U67]. Despite its easy implementation and low complexity, the ED does not perform in low signalto-noise-ratio (SNR) and cannot differentiate… CONTINUE READING
