METHOD FOR FORMING NOISE-LIKE SIGNALS Russian patent published in 2023 - IPC H04B1/69 H04L27/20 

FIELD: radio engineering.

SUBSTANCE: two carrier frequency signals are formed, shifted between themselves in phase by ninety degrees, and a clock frequency signal. Binary quasi-orthogonal pseudo-random sequences, synchronizing (SP) and informational (IP), are formed from the clock frequency signal. At each repetition period of the SP, a modulated sequence (MP) is formed by cyclic shifting of the IP relative to the SP. A compositional sequence is formed by switching the MP and SP elements with a clock frequency signal. One of the carrier frequency signals is manipulated in the phase of the composite sequence, and the second one is manipulated by the sequence obtained by modulo two addition of the clock frequency signals with the elements of the composite sequence, and they are summed.

EFFECT: reduction up to ninety degrees of signal phase jumps occurring on simultaneous change in sequence values, which are phase-manipulated by carrier frequency signals.
