FIELD: radio engineering, communications.
SUBSTANCE: receiving device with digital processing of received signals comprises an antenna, an attenuator, receiving (main and additional) channels, a multi-channel multiplier, a memory device of threshold level, a multichannel digital comparator and a multichannel "AND" block. Each receiving channel accordingly comprises serially connected a linear tract of a receiver, an analogue-to-digital converter, a device of data accumulation and a processor of discrete Fourier transform, outputs of which are outputs of the main (additional) receiving channels. The number of channels of the multichannel multiplier, the multichannel digital comparator and the multichannel "AND" block is equal to the number of outputs of the processor of discrete Fourier transform.
EFFECT: increased noise immunity of a receiving device with digital processing of received signals due to elimination of false signals at frequencies of intermodulation noise.
