Correlation systems of discrete information transmission with noise carrier oscillation and switching of the delays are considered,  allowing substantially stabilize a dispersion of noise signal in the channel, and by that to increase a secretive of transmission. The  opportunity of exception of requirements on high identity of sizes of delays in reception and transmitting parts of system is investigated at ultra-wide band bearing noise fluctuation due to application of the pseudo quadrature processing principle in a receiver part. Calculated examples of processes mean values on an output of the receiver are resulted at transfer of zero and one, that confirm  efficiency of the offered principle.
