Phase-Modulated Signals Synthesis Method to Control Information Transmission Channels

The paper analyzes the methods of signal synthesis to control information transmission channels. The prospect of using phase-modulated signals to control information trans-mission channels is substantiated. Based on the results of the comparison, it is shown that the triangular law of phase change increases the reliability of monitoring the technical condition of information transmission channels. At the same time, the triangular law of phase change is technically easier to implement compared to the harmonic one. An expression is proposed for the optimal value of the phase modulation index for triangular phase modulation. The sensitivity of the tested system is calculated for the optimal phase modulation index for sinusoidal and triangular modulations. A method for synthesizing phase-modulated signals with insignificant values of the phase modulation index and high accuracy of their assignment in the low-frequency range of the envelope and non-existent is proposed. The results obtained make it possible to synthesize the optimal parameters of phase-modulated signals for monitoring information transmission channels. The results of the study are proposed to be used in communication systems when monitoring the characteristics of the reliability and validity of information transmission channels.
