CAUSED BY THE INTERFERING RADIO SIGNALS INTERFERENCE COMPENSATION DEVICE, DURING THE RADIO SIGNALS WITH PHASE MODULATION RECEPTION

摘要

FIELD: radio equipment and communication.;SUBSTANCE: invention relates to the radio equipment and can be used for compensation of caused by the interfering radio signals interferences, during the radio signals with phase modulation reception. Caused by the interfering radio signals interference compensation device during the radio signals with phase modulation reception contains the intermediate-frequency amplifier, which output is in parallel connected to the main reception, channel consisting of a in-series connected amplitude limiter and the phase detector, which output is connected to the output adder one of the two inputs, and the additional reception channel with installed at its input amplitude detector, at that, in the additional reception channel the additional analog-to-digital converter, the digital voltage generating unit and the digital-to-analog converter are installed, and in the main reception channel the adjustable delay line is installed, which ensures coming to the output adder two inputs signals synchronization to provide for the voltage compensation, proportional to the caused by the interfering radio signal presence useful radio signal parasitic phase shift.;EFFECT: ensuring caused by the interfering radio signal interference compensation, with the useful radio signal amplitude small excesses over the interfering radio signal amplitude.;1 cl, 3 dwg
