FIELD: radio engineering; radio stations and transceiving centers.
SUBSTANCE: proposed device that has electronically tuned receiver incorporating built-in pulse-noise blanking unit connected to antenna output through electronically controlled attenuator and channel quality fine estimate unit is provided, in addition, with noise envelope coarse estimate unit, invalid-character erasing signal sensor, blanking threshold regulator, level attenuation unit, and automatic control unit for parameter adjustment.
EFFECT: enhanced precision of best radio communication channel selection and enhanced noise immunity in reception.
