METHOD OF INCREASING NOISE IMMUNITY OF SPEECH TRANSMISSION AND PORTABLE RADIO STATION-GATEWAY OF LOW POWER Russian patent published in 2025 - IPC H04B7/00 H04B1/00 

FIELD: radio communication.

SUBSTANCE: invention relates to radio communication and can be used to transmit information over digital communication channels. Low-power radio station-gateway includes at least two transceiving modules of low-speed noise-immune digital communication channel, using spectrum spreading method, implementing on the transmitting side the parallel data transmission of the preliminarily demultiplexed encrypted data stream from the vocoder output, at the receiving side, parallel reception by at least two receivers performing demodulation, depacketting and noise-immune decoding with subsequent multiplexing of streams, decoding and conversion of digital data into a speech signal by a vocoder.

EFFECT: high noise immunity is provided by increasing the redundancy of each individual low-speed digital communication channel in proportion to the number of such channels used; since each communication channel transmits part of the voice message, the secrecy of the voice message is increased; gateway function of a portable radio station-gateway is realized using a transceiving module of a high-speed digital communication channel for communication with at least one smartphone.
