RADIO RECEIVING DEVICE WITH THE DITHER SIGNAL AMPLITUDE SWITCH CONTROL Russian patent published in 2018 - IPC H04B1/64 

FIELD: radio equipment and communications.

SUBSTANCE: invention relates to radio equipment

and can be used to create promising radio facilities with programmable architecture with digital signal processing directly at the radio frequency under the influence of blocking signals to ensure stable radio communication in complex interference environment. Radio receiving device with dither signal amplitude switch control contains: in series connected input circuits unit and pre-selector, adder, analogue-to-digital converter (ADC), digital receiving path and demodulator, which output is the device information output; in series connected dither signal generator and key, which output is connected to the adder second input; sampling frequency source comprising N reference oscillators, whose outputs are connected to respective switch inputs, which output is the sampling frequency source output and connected to the ADC clock input, as well as in series connected the received signal amplitude calculator, which input is connected to the ADC output, and digital comparator, which output is connected to the key first input.

EFFECT: technical result is increase in the dynamic range by the useful signal blocking while preserving the radio receiving device parameters by selectivity.
