The problem of ensuring quality of information transfer in noise-immune radio-control channels is investigated. Methods are considered for designing signal-code structures that possess prescribed properties that guarantee noise immunity, resistance to masquerades, and hiding of radio-control channels.

An original technique is proposed for formation of pseudorandom sequences on the basis of coding methods. The synthesis of large ensembles of signals with improved autocorrelation properties is theoretically substantiated. Methods of correlation analysis are used to study auto-and crosscorrelation properties of sequences being formed.

621.391Asymmetric coding schemes are developed that are constructed with the use of algebraic geometric codes. Basic analytical expressions are obtained that connect the parameters of algebraic geometric codes with the parameters of asymmetric coding schemes based on these codes.
