Abstract
A method for detecting co-channel interference in a frequency-modulated multiplexed radio signal, the method including verifying that the multiplexed radio signal has a symmetric passband; detecting and counting a plurality of positive noise peaks and a plurality of negative noise peaks in the multiplexed radio signal during a predetermined measurement duration; calculating a rate of positive or negative noise peaks among the plurality of peaks; and determining a score characteristic of a probability that co-channel interference exists in the multiplexed radio signal on the basis of the rate of positive or negative noise peaks.
