Abstract
FIELD: radio engineering, possible use in radio-technical systems, meant for receiving broadband signals on the background of spectrum-concentrated interference.SUBSTANCE: device has block for selection of minimal signal, N frequency channels, serially connected broadband filter and block for amplification and transformation of frequency, output of which is connected to inputs of frequency channels, outputs of frequency channels are connected to appropriate outputs of adder. Each frequency channel contains serially connected narrowband filter, input of which is input of frequency channel, first amplifier, amplitude detector, output of which is connected to appropriate input of block for selection of minimal signal, and subtracter, connected serially, second amplifier, amplification adjustment input of which is connected to appropriate input of input adder. Also, device contains, serially connected, additional adder, input of which are connected to outputs of threshold devices, attenuator with controllable fading value, input of control signal of which is connected to output of additional adder, and signal input is connected to output of block for selection of minimal signal, and third amplifier, output of which is connected to other inputs of subtracters and to input for controlling amplification coefficient of block for amplification and transformation of frequency. Threshold element is provided in each frequency channel, input of which is connected to output of subtracter, while output is connected to appropriate input of additional adder, while adder output is the output of device.EFFECT: increased ratio of useful signal power to interference power under conditions of non-stationary interference situation.3 dwg
