METHOD FOR SELECTING WORKING FREQUENCIES FOR RADIO-LINES OF IONOSPHERE WAVES Russian patent published in 2007 - IPC H04B1/00 H04B7/00 

FIELD: radio communications, possible use for operative selection of working frequencies at stations of ionosphere wave and frequency-dispatch service of radio-centers under conditions of changing interference situation and with limited frequency resource.

SUBSTANCE: selection of working frequencies is performed based on conditions of frequencies serviceability as a result of reflection from ionosphere and signal-interference situation with consideration of the condition, when ratios of intensity of signal and interference are less than minimally allowed ratio of signal/ noise level z_add., and also, when current probability of receipt error ρ^T _err. is less than predetermined maximally allowed error probability ρ^max _err. with consideration of coefficient of mutual difference of signal and information structures in time-frequency area.

EFFECT: creation of method for selecting working frequencies for radio-lines of ionosphere waves, ensuring increased trustworthiness when determining serviceability of radio frequencies.
