The method for the detection of Carrier-in-Carrier signals based on the calculation of fourthorder cumulants is proposed. In accordance with the methodology based on the "Area under the curve" (AUC) parameter, a threshold value for the decision rule is established. It was found that the proposed method provides the correct detection of the sum of QPSK signals for a wide range of signal-to-noise ratios. The obtained AUC value indicates the high efficiency of the proposed detection method. Thedoi:10.5121/csit.2019.90503 fatcat:idxsjl7hmjai3iu76bmvxatqz4
