Cyclostationarity-based detection
WebThis paper extends the BD method, which is based on maximizing the second-order cyclostationarity, to maximize the generalized Gaussian cyclostationarity to extract fault features from non-Gaussian signals. In addition, the generation of the weighting matrix now incorporates the estimation of fault frequencies. WebOct 1, 2015 · The cyclostationarity feature detection method exploits the cyclic stationary features of the received signals for detecting primary user transmissions [ 19, 20 ]. Periodicity in the signal or in its statistics, like mean and autocorrelation, results in cyclostationarity features [ 21 ].
