The noise immunity of the invariant system of information transmission in the presence of weak correlation contacts

The invariant system of information processing based on synchronous detection is considered. It is assumed that by the parameters estimation of such a system the nearest readings of the subcarrier are interfered with the additive noise; these readings are weakly correlated. The comparison of the quantitative estimation of such a system operation with quantitative indications of the known invariant system by non-correlation of noise readings is realized.
