FIELD: radio communications, possible use for operative selection of working frequencies at stations of ionospheric-wave and frequency-dispatching service of radio centers.
SUBSTANCE: device for automatically selecting working frequencies additionally features blocks for: memory for probability of allowed error, predicted value of signal power, determining current probability of erroneous receipt, averaging and comparing mutual difference coefficient at various operation modes, fast Fourier transformation, determining conditional mutual difference coefficients, memorizing Fourier coefficient of interference, memorizing Fourier coefficients of standard signals, determining usability of frequencies, memorizing usable frequencies, memorizing unusable frequencies, culling of frequencies with consideration of difference coefficient, block for selection of optimal frequency and operation mode.
EFFECT: increased trustworthiness of selection of optimal working frequencies with appropriate operation mode.
