RADIO LINK WITH AUTOMATIC ADJUSTMENT OF SPECTRUM PARAMETERS WITH INTERFERENCE COMPENSATION Russian patent published in 2024 - IPC H04B1/12 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering and can be used in communication systems, performing automatic adjustment of radio signal spectrum parameters in order to ensure electromagnetic compatibility with radio electronic means operating simultaneously with a radio transmitting device in common areas of space and in the radio frequency bands of the out-of-band radiation of the radio transmitting device to provide maximum power and reduce the probability of a bit error when receiving a signal by matching the filter parameters of the receiving device with the spectral characteristics of the received signal in the radio link, as well as continuous compensation of additive Gaussian noise in the receiving channel regardless of the presence of the signal and its level. Radio link with automatic adjustment of spectrum parameters with interference compensation provides measurement of average power of additive Gaussian interference regardless of the presence of a signal and its level using the additionally introduced second and third channels of autocorrelation processing and compensation of interference at the output of the additionally introduced first channel of autocorrelation processing, which is the input of the digital computer.

EFFECT: increasing the signal-to-noise ratio at the first input of the digital computer of the radio receiving device by compensating for additive Gaussian interference at the output of the analogue-to-digital converter.
