DEVICE FOR AUTOMATIC SELECTION OF OPERATING FREQUENCIES Russian patent published in 2003 - IPC

FIELD: radio communications. SUBSTANCE: device that can be used for optimal on-line selection of operating frequencies at ionosphere-wave and frequency-supervision services of radio centers at the same time analyzing block of noise parameters (current values, mean values, noise level dispersions, and the like) has antenna switch, radio receiver, filter unit, analyzing unit, first, second, and third decoders, antenna number memory unit, frequency number memory unit, filter number memory unit, noise threshold level memory unit, control unit, distribution unit, additional noise parameter evaluation unit, frequency characteristic estimation unit, frequency adaptability estimation unit, frequency rejection unit, and optimal frequency selection unit. Novelty is introduction of distribution unit, additional noise parameter evaluation unit, analyzed frequency weight evaluating unit, frequency adaptability estimation unit, frequency rejection unit, and optimal frequency selection unit that take into consideration combination of existing tokens in analyzing and selecting operating frequencies of noise parameters. EFFECT: enhanced reliability of operating frequency choice. 14 cl, 26 dwg
