METHOD OF INCREASING SIGNAL-TO-NOISE LEVEL (RATIO) USING "DISTURBANCE DAMPING PRINCIPLE" Russian patent published in 2013 - IPC H04B1/10 

FIELD: information technology.

SUBSTANCE: method of increasing signal-to-noise level (ratio) in spatial selection of signals is characterised by that it includes an operation for synchronisation thereof and then summation of all components of the same signal source, received at spaced points, mutual spatial coordinates of which should be located in a region whose maximum dimensions are much larger than the maximum wavelength of the received wavelength range. Another method of increasing the signal-to-noise level (ratio) with variation of frequency-time parameters of the signal includes an operation for synchronising frequency-time elements of the input signal and then summing all frequency-time elements of the input signal formed at the transmitting side and for which frequency-time parameters of noise realisations, received with the signal in the same band, must satisfy independence conditions for random values.

EFFECT: extracting information during reception at noise levels exceeding the signal level.
