METHOD FOR DETECTING RESPONSE INTERFERENCE IN RADIO CHANNELS WITH DISCRETE SIGNALS WITHOUT AMPLITUDE MODULATION Russian patent published in 2021 - IPC H04B1/10 

FIELD: radio engineering.

SUBSTANCE: invention relates to the field of radio engineering and can be used in radio communication systems with the ability to detect the impact of response interference. In the method for detecting response interference in radio channels with discrete signals without amplitude modulation, the decision on the impact of response interference is made taking into account both the dispersion of the amplitudes of the demodulated signal elements and the duration of these elements. On a block of n signal elements, the number of elements is counted at which the variance of the signal amplitude is more than 1.5 times different from the pre-calculated threshold, and also those demodulated symbols are counted, the duration of which differs from the reference value of the duration by more than 20%. If the total number of counted symbols exceeds the value of 10% of the value of n, then a decision is made on the effect of the return interference.

EFFECT: increase in the accuracy of determining the response interference.
