FIELD: radio engineering; communication.
SUBSTANCE: invention relates to radio engineering and communication and can be used to build circuit and design solutions for signal generators, solid-state power amplifiers and antenna-feeder systems in the short-wave range. Using a given program, evaluating the quality of demodulation based on the known parameters of the frequency and phase of the signal, symbol rate, signal-to-noise ratio, wherein the functional units of the two modules are controlled, wherein the four analogue-to-digital converters operate synchronously from one master oscillator for the receiving and transmitting paths with a quantization step of not more than 1.5×10-5, and to eliminate intersymbol interference and operation in the main Nyquist window, the conversion frequency is selected in range from 65 to 250 MHz, wherein such architecture enables to receive a signal from four antennae simultaneously to build a radio receiving device, wherein synchronous reception of radio signals from four different antennae enables to implement adaptive processing algorithms with interference compensation and frequency adaptation thereof.
EFFECT: improved reception of information in conditions of signal fading due to its propagation along a radio channel, as well as compensation of interference and their adaptation as to frequency.
