DATA TRANSMISSION SYSTEM AND METHOD Russian patent published in 2025 - IPC H04J11/00 H04L27/36

Abstract RU 2839444 C1

FIELD: data transmission.

SUBSTANCE: data transmission system comprises a plurality of modems which exchange data with each other on orthogonal carriers and have a signal transmission module, a signal reception module and a module for adapting the system to environmental conditions. Signal transmission module transmits information on the state of each carrier in the signal and recommendations on correcting the amplitude of transmitted carriers and limiting the number of active carriers. Signal receiving module measures signal/noise ratio on each carrier and average deviation of active carriers during demodulation, receives information on the state of each carrier, the recommended correction of the amplitude of transmitted carriers and the recommended limitation of the number of active carriers. Adaptation module changes the amplitude of carriers in signals generated by the signal transmission module, and generates recommendations on correcting the amplitude of transmitted carriers and limiting the number of active carriers.

EFFECT: high rate of transmitting data with minimum error level in strongly inhomogeneous media with time-varying frequency-inhomogeneous interference.
