摘要：

Based on the developed methodology for analyzing the noise immunity of receiving radio signals with quadrature phase shift keying (QPSK), the probabilities of a bit error in the presence of interference with linear frequency modulation were calculated and compared with the influence of harmonic interference. A technique is presented without calculating the probability of correct reception, using conditional transition probabilities between positions of the signal constellation, which has no restrictions on signal and interference levels.
