Method for the Detection of Carrierin-Carrier Signals Based on Fourth-Order Cumulants


Vasyl Semenov , Pavel Omelchenko and Oleh Kruhlyk, Delta SPE LLC, Kiev, Ukraine


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. The advantage of the proposed detection method over the “radiuses” method is also shown.
