On the basis of mathematical apparatus of indicators of events the generalized expression of average probability of the correct reception of sequence from m elements not fading M-QAM a signal in the form of a functional from an interference of the arbitrary structure is received.
With application of calculus of variations by criterion in the form of a minimum of average probability of the correct re-ception of an element of a considered signal the most unfavorable interference to the correlative receiving-solving device of this signal is synthesized at restriction on average power of an interference.
On an indicator in the form of average probability of the correct reception of sequence from m elements M-QAM of a signal the estimation of interference immunity of its reception in the conditions of influence synthesized, harmonic and PSK interference is fulfilled.
Materials are stated on 12 pages, are illustrated by 2 figures, the bibliographic list contains 8 sources.
