Π°The article presents a system of methods for optimizing the parameters of signal-code constructions with orthogonal signals and Reed-Solomon codes, as well as their processing modes when receiving with soft decoding under conditions of signal-noise environment uncertainty while simultaneously acting on a channel with pseudo-random restructuring of the working the frequency of two interference-barrage and concentrated in part of the frequency band. The optimization takes into account the boundary value and the worst value for the channel of the part of the band of pseudo-random tuning of the operating frequency, in which the concentrated interference act

ΠΎΠ²ΠΎΠΉ ΠΎΠ±ΡΡΠ°Π½ΠΎΠ²ΠΊΠ΅A coherent data transmission channel with pseudo-random tuning of the operating frequency (FH) is considered, a concatenated code based on an ensemble of orthogonal signals and a Reed-Solomon code, with various reception-decoding algorithms under conditions of simultaneous action on the channel of two interference β a barrage and a FH concentrated in a part of the band.
The estimates of the boundary value of the part of the FH band covered by the interference, the characteristics of the optimal concatenated code, are obtained, and also the receive-decoding algorithm is selected, in which the boundary value of the part of the band covered by the interference takes the maximum value in a given interference environmen

The characteristics are obtained as a result of statistical simulation of the algorithm for strobeless identification of trajectories, synthesized by a method based on the theory of optimal filtering of discrete-continuous Markov random processes. These characteristics are compared with the characteristics of strobeless and strobe identification in radar identificatio

ΡΠ΅ΡΠ΅Π½ΠΈΠΉThe characteristics of noise immunity of a coherent data transmission channel with Frequency Hopping Spread Spectrum (FHSS), orthogonal signals and Reed-Solomon code with its soft decoding have been obtained using spectral density estimation of interference power, which is a combination of two Gaussian noise interference, they are barrage jamming and one concentrated in the FHSS band part. It is found that when the volume of an orthogonal signals ensemble increases, noise immunity rises due to the accuracy growth of the spectral density estimation of the interference power, which in turn provides an accuracy growth of posterior probability estimation used for soft-decision decodin
