RADIO RECEIVING DEVICE WITH SMOOTH CONTROL OF BLURRING SIGNAL AMPLITUDE Russian patent published in 2025 - IPC H04B1/64 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering and can be used to create advanced radio equipment with programmable architecture with digital signal processing directly at radio frequency in conditions of blocking signals to ensure stable radio communication in a complex interference environment. Radio receiver with smooth control of the blurring signal additionally comprises series-connected device for controlling the amplitude of blurring signal (11) and scaling unit (13). Scaling unit consists of series-connected digital blurring signal generator (6) and digital multiplier (14). Second input of the digital multiplier is the input of scaling unit (13). Output of digital multiplier (14) is the output of scaling unit (13) and is connected to the input of digital-to-analogue converter (DAC) (12). Output of the DAC is connected to the second input of adder (2). Output of the amplitude of received signal (10) is connected to the input of the device for controlling the amplitude of blurring signal (11).

EFFECT: increased dynamic range of intermodulation in conditions of presence of blocking interference at the input of the receiver while maintaining dynamic range of blocking.
