碩士 === 元智大學 === 通訊工程學系 === 99 === In this thesis, a signal spectrum sensing scheme for Cognitive Radio Network based on distributed detection over Rayleigh fading channel is provided. On-off keying signal modulation is simulated to signal detection behavior, a sensing technique which is called Coherent Amplitude Detection is used in sensor node, and Majority-Voting Combining is proposed for fusion center in this thesis. Finally, it is showed that the Miss-Detection probability for Majority-Voting Combining based on distributed detection is better than Selection Combining if the False-Alarm probability is limited to a constant.
