Sadchenko A. Cyclical signals with amplitude - phase and discrete-frequency manipulation invariant to m-shift

The thesis is devoted to syntheses of new classes noise-shape APM and DPM signals invariant to m-shift and allowing using the efficient devices for coordinateded processing. The frequency method of syntheses of multilevel numeric sequences (MNS) invariant to m-shift and having ideal periodic autocorrelation functions Is developed. The analysis a peak-factor MNS and systems APM signals which synthesized on their base Is organized. It Is found systems APMm signals, which have noise-immunity above in contrast with existing classes APM signals. Schemes for coordinated processing the systems APM signals is proposed. It is organized the calculations of noise-immunity of systems APMm signals on base MNS and designed devices for their processing . The quantitative results of comparison of efficiency an decoders on base MNS invariant to m-shift and MNS on base of square-law residues in Galois’ fields are brought
