FIELD: reception and processing of signals.
SUBSTANCE: invention relates to equipment for receiving and processing signals and can be used to create radio equipment. Radio receiving device comprising preamplifier (1), analogue-to-digital converter (2), correcting nonlinear element (3.1) and digital signal processing (DSP) unit (4), N blank filters (5.1...5.N), N-1 correcting nonlinear elements (3.1...3.N) and adder (6), the output of which is connected to the input of DSP unit (4). Inputs of N blank filters (5.1…5.N) are combined and connected to the output of ADC (2), and the outputs of N blank filters (5.1…5.N) are connected to the inputs of the corresponding N correcting nonlinear elements (3.1…3.N).
EFFECT: reduced nonlinear distortions of the received signal in the entire operating frequency range of the radio receiver.
