- W3134118223 abstract "The main objective of the thesis is to devise a reliable non-cooperative spectrum sensing system that is able to detect noiselike signals. We harness the strength of cepstral analysis to develop a system able to detect spread spectrum signals. We have proposed the autocepstrum approach to detect noise-like signals. The proposed techniquesshowed reliability for detecting spread spectrum and Ultra-Wide Band (UWB) signals. For improved detection process, we smoothen the fluctuations of the autocorrelation estimators by using the Total Variation Denoising (TVD) algorithm. We formulate a wideband spectrum sensing problem which based on detecting the spectral boundaries followed by the PU detectionphase. In this regard, we introduced the Differential Log Spectral Density (DLSD) algorithm to identify the spectral boundaries of the target wideband spectrum. For the PU detection, we introduced the BaseBand-AutoCepstrum Detection (BB-ACD) which extracts the baseband information before applying the auto-cepstrum detection technique to take into account the frequency uncertainty that may result from falsely detected spectralboundaries. Finally, an enhanced power cepstrum is introduced by the Cepstral Covariance Detection (CCD) for detecting digitally modulated signals." @default.
