RADIO COMMUNICATION DEVICE Russian patent published in 2020 - IPC H04B7/02 

FIELD: radio engineering and communications.

SUBSTANCE: invention relates to radio communication engineering and is intended, in particular, for use in multichannel devices for transmitting and receiving radio signals. Radio communication device comprises on the transmitting side a switch, an analogue-to-digital converter and a transmitting antenna, wherein the switch inputs are information inputs of the radio communication device, and the output of the switch is connected to the input of the analogue-to-digital converter. At the receiving side, the device has a receiving antenna, a receiver, a digital conversion matrix, indication and recording equipment, which is the output of the radio communication device. Transmitting and receiving sides are equipped with power supply units. Output bus of analogue-to-digital converter is connected to shaper of multiplicative signal relative to beginning of its count, output of which is connected through in-series connected memory unit with alphabet of signals, controlled transmitter-generator with a transmitting antenna, which is connected via a radio channel to a receiving antenna of the receiving side connected through a receiver to a multichannel correlator, to the second input of which a first information bus connected to a signal alphabet memory unit is connected. Second information bus of multichannel correlator is connected to matrix of digital conversion. Radio communication devices of all subscribers are identical and include the transmitting and receiving sides, as well as a memory unit with a signal alphabet.

EFFECT: high noise-immunity by improving the shape of the autocorrelation function of carrier signals while eliminating losses in the value of the signal-to-noise ratio associated with the Doppler dispersion.
