METHOD FOR ACTIVE CONTROL OF WORKING FREQUENCIES WITHOUT INTERRUPTION IN INFORMATION TRANSMISSION Russian patent published in 2021 - IPC H04B17/18 H04B17/30 

FIELD: radio engineering.

SUBSTANCE: invention relates to the field of radio engineering and is intended for application in radio communication systems employing a mode with pseudo-random reconfiguration of the working frequency. The effect is achieved by the fact that the entire time cycle of transmission is additionally divided into analysis, frequency vector transmission, and data transmission sub-cycles. The algorithm for pseudo-random selection of working frequencies and the parameters of the signal used therein remain unchanged in all sub-cycles, and a formed quaternary quadrature manipulation signal is used for data transmission in all sub-cycles. In the analysis sub-cycle, a sample data block is combined with the information block so that odd bits are attributed to the sample block and even bits are attributed to the information block. In the duration of the frequency vector transmission sub-cycle, the bit sequence of the frequency vector is combined with the information bits so that the odd bits are attributed to the frequency vector and the even bits are attributed to the information block and transmitted to the correspondent.

EFFECT: combination of technical procedures for controlling the suitability of working frequencies and information transmission of radio communication systems.
