FIELD: communication facilities.
SUBSTANCE: system for evaluation of channel contains components of filtration which selectively scales multitude of bearing as function of position of bearing multitude in the frame of frequency range, herewith bearing multitude contains at least one data bearing and at least one control bearing. Then component extrapolates measuring result from at least one control bearing, herewith channel is evaluated as function from extrapolated measurement result. Scaling of bearing simplify reduction of influence of self-noises level, associative connected to evaluation of channel. Filtration component can be used in transmitting device or receiving device and can be activated and deactivated as function of defined type of data packet.
EFFECT: reduction of error of channel's evaluation by means of reduction of influence of self-noises level.
