METHOD FOR IMPROVING THE OPERATIONAL EFFICIENCY OF AN ADAPTIVE DECAMETRIC RADIO COMMUNICATION SYSTEM Russian patent published in 2020 - IPC H04L27/26 H04L5/00 

FIELD: radio engineering and communication.

SUBSTANCE: invention relates to radio communication and can be used for adaptive systems and decametric radio communication systems and their increase good service factor ratio and operation under conditions of initial uncertainty and complicated interference environment. Disclosed is a method for improving the operational decay of an adaptive decametric radio communication system, the difference from the prototype is that the adaptive decametric radio communication system additionally includes service information receiving-transmitting unit; this receiving-transmitting unit consists of a program-defined radio system, connected by a digital data bus with a computing device, the output of which is connected to the digital-to-analogue converter, and input is connected to analogue-to-digital converter, connected to signal output of high frequency amplifier of first receiving channel, by means of which low-speed noise-protected exchange of noise-like phase-shift keyed signals transmitted through feedback channels is carried out, as well as ringing signals when it is necessary to establish communication, signals of response combinations by the called subscriber and receipts by the communication initiator. Besides, an adder connected to the signal output of the digital to analogue converter of the service information receiving-transmitting unit and the signal processing unit of the computing device, which output is connected to input of broadband power amplifier of transmitting path; further high-speed transmission of useful information is carried out.

EFFECT: main task, which solution is aimed at is improvement of operating condition of radio communication system, which is achieved by introducing an additional low-speed noise-protected radio communication channel which realizes a method of exchanging service information of an adaptive decametric radio communication system with reliability of not more than 1 error per 1000 bits and a signal-to-noise ratio of up to -30 dB.
