METHOD FOR PROVISION OF TECHNICAL AVAILABILITY OF RADIO LINES WITH FREQUENCY HOPPING Russian patent published in 2008 - IPC H04B1/713 

FIELD: radio communications.

SUBSTANCE: at the transmitting end information packets are formed by adding to them destination "address" and service information, transmitter carrier frequency is tuned, radio signal is emitted to the receiving end of radio link where the transmitted signal is received simultaneously at all frequencies, after appropriate conversion the information signal is supplied to the information receiver; at the receiving end of radio link control receivers check frequencies for interference along with radio signal receiving, generate control information to tune the transmitter at the transmitting end of radio link to the frequency that is free from interference, form information packets by adding to them the control information to tune the transmitter at the transmitting end of radio link, tune carrier frequency of the transmitter at the receiving end of radio link, modulate carrier frequency of the transmitter at the receiving end by the formed information packet, emit the obtained radio signal to the transmitting end of radio link where it is received along with radio signal transmitting simultaneously at all frequencies, the control information is retrieved to tune the transmitter at the transmitting end of radio link to a frequency that corresponds to code of the next cycle of the Pseudo-Random Sequence (PRS), which is free from interference; at that, at the receiving end of radio link control receivers, after signal receiving, provide for forecasting of signal-to-noise ratio variation at the frequencies that correspond to codes of the next cycle of all PRSes, analysis signal-to-noise ratio, and tuning to the nearest frequency, which is free from interference, and no signal-to-noise degradation is forecasted.

EFFECT: provision of required technical availability due to forecasting of signal-to-noise ratio variation at inputs of control receivers.
