METHOD FOR FORMING SIGNAL WITH PSEUDORANDOM TUNING OF WORKING FREQUENCY TUNING Russian patent published in 2018 - IPC H04B1/713 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering and can be used in radio communication systems using broadband signals. Method for generating a signal with a pseudorandom tuning of the operating frequency (PTOF) is based on the generation of the primary signal S(t) in the basis of the spline-character functions (BSCF), modulation by its digital sequence C(t), the formation of a reference oscillation M(t), multiplying the modulated signal S'(t) with a reference oscillation M(t). Frequencies ƒ₁, ƒ₂, … the reference oscillation M(t) is determined in accordance with a predetermined random numerical code sequence O₂(t). Values of the variable BSCF parameters are selected in accordance with a predetermined pseudorandom code numerical sequence O₁(t) in synchronism with the change in the frequency of the reference oscillation M(t), wherein the pseudorandom code sequence O₁(t) are formed as C = A constituents , , where A – number of changing parameters of BSCF.

EFFECT: technical result of the invention is the development of a method for generating a signal with a pseudorandom tuning of the operating frequency (PTOF), providing increased structural security of the formed signal.
