FIELD: mining industry.
SUBSTANCE: method includes continuous calculation of possibility distribution function of signal amplitude with noise, value of amplitude with noise is determined from it, matching minimum of this function, which is then taken as threshold level. This allows automatic adjustment of threshold level for different amplitudes of signal and noise, that is important for receiving information from deep wells along long communication lines with high level of broadband interference.
EFFECT: higher precision.
