METHOD FOR GENERATING A SIGNAL WITH SOFTWARE TUNING OF THE OPERATING FREQUENCY WITH VARIABLE PARAMETERS Russian patent published in 2022 - IPC H04B1/10 H04B1/713 

FIELD: radio engineering.

SUBSTANCE: invention relates to the field of radio engineering and is intended for use in radio communication systems (RCS) with programmed restructuring of the operating frequency (PROF), using anti-jamming radio signals. A method for generating a signal in the mode of programmed tuning of the operating frequency (PROF) with variable modulation parameters includes generating a primary signal S(t) in a nonharmonic basis, generating a reference oscillation M(t), multiplying a modulated signal S(t) with a reference oscillation M(t) , replacement on the transmitting side of each element of the information sequence with radio pulses, the formation of a frequency modulation signal at the operating frequency, transmission of the generated signal to the receiving side, on the receiving side demodulation of the frequency modulation signal based on the parameters specified by the sequence O₁(t) and replacing radio pulses with logical elements of the information sequence, synchronous change of code words based on the sequences O₁(t) and O₂(t) with each change in the frequency of the reference vibration M(t). The frequencies of the reference oscillations M(t) f₁, f₂, … are determined in accordance with a given random code sequence O₂(t). Radio pulses are obtained from wavelet functions of a given order. The operating frequency is determined by the code sequence O₂(t). The private modulation index, the order of the wavelet function and the emission time are selected in accordance with the code sequence O₁(t) synchronously with the change in the frequency of the reference oscillation M(t). The information sequence is transmitted to the recipient of the message.

EFFECT: increased signal noise immunity.
