Cyclostationarity-Based Detection of Randomly Arriving or Departing Signals

This paper addresses the problem of detection of randomly arriving or departing primary user (PU) signals in cognitiveradio systems. The detection problem of the dynamic PU signal is modeled as a binary hypothesis testing problemwhere the PU signal might randomly depart or arrive during the sensing...
