Abstract:

The distinctive features of modern radio transmission lines are high requirements for the quality of transmitted data, the bandwidth of communication channels, as well as noise immunity and cryptographic protection of information transmitted over the air. At the same time, at the present stage of radio engineering development, communication equipment developers are creating new signal-code designs, methods and algorithms for digital signal processing, ways to increase noise immunity. Well-known domestic high-speed radio transmission lines are based on the use of promising COFDM signals (multiplexing with orthogonal frequency division of channels with channel coding), which allow transmitting information from target loads at a speed of several tens of megabits per second to several hundred megabits per second. At the same time, both at the stage of formation of COFDM signals and in the process of transmitting information over the radio channel, various destabilizing factors arise that affect the quality of communication. To quantify the main destabilizing factors affecting the availability coefficient of multipath radio channels, a mathematical apparatus presented in this article has been developed.
