|Abstract:||This paper is concerned with detector design and performance analysis for spectrum sensing of phase-modulated signal in cognitive radio systems. Under the maximum a posteriori probability criterion, the optimal detector which outperforms the popular energy detector is derived, and its detection and false-alarm probabilities that describe the receiver operating characteristic (ROC) are analyzed. These probabilities are obtained as explicit, closed-form expressions, which show analytically ROC behavior as a function of various system parameters such as the signal-to-noise ratio and the number of data samples. The theoretical analysis and results are validated by computer simulations. © 2013 IEEE.|
