On the basis of the mathematical apparatus of events indicators, are deduce of formula for the probability of correct reception of a sequence from m signal elements of a non-fading M QAM signal in a correlation receiver-solver against a background of non-fading pulsed harmonic interference.
The analysis of the dependences of the probability of the correct reception of a sequence of the signal and the interference-to-signal ratio at the input of a suppressed receiver is performed for a fixed value of this probability on various signal and interference parameters.
The received dependences can be useful to the experts who are engaged in an estimation of interference immunity of means of a radio service in the conditions of station and deliberate noises.
Materials are stated on 10 pages, are illustrated by 2 figures, the bibliographic list contains 9 sources.
