FIELD: radio engineering.
SUBSTANCE: invention relates to radio engineering and can be used for formation of noise-immune radio signals. Method of forming of noise-immune signals provides preliminary numerical binary pseudorandom sequence, where values of zeros and units are modulated by previously formed pairs of radio pulses, representing the product of opposite by-orthogonal Wavelet functions and fragments of signals with linear frequency modulation.
EFFECT: technical result consists in increase of noise-immunity of radio signals in communication systems by increasing the width of spectrum (of occupied bandwidth).
