Spectrum sensing is one of component in cognitive radio (CR). The sensing algorithm that usually used is the matched filter and the energy detector. Because there is a shortage in energy detector, which is very sensitive to noise power uncertainty. Then formed a new method based on the covariance matrix of the received signal. In this paper analysis on cognitive radio spectrum sensing using signal...
We present a survey of state-of-the-art algorithms for spectrum sensing in cognitive radio. The algorithms discussed range from energy detection to sophisticated feature detectors. The feature detectors that we present all have in common that they exploit some known structure of the transmitted signal. In particular we treat detectors that exploit cyclostationarity properties of the signal, and detectors...
