FIELD: information technologies.
SUBSTANCE: creation of spreading code set is started with definition of the first and second chaotic pseudorandom noise codes, having similar delta functions of an autocorrelation function and a low cross correlation function. The next pseudorandom noise codes are produced by addition of a calculated code to a set of already pseudorandom noise codes, if the specified code has similar delta-functions of the autocorrelation function and low cross correlation function with already defined pseudorandom noise codes, rejection of a calculated code, if the specified terms for addition to the set of already determined pseudorandom noise codes are not met, modification of an index and repetition of stages, starting from the stage of calculation of a pseudorandom noise code until a cardinal number of the set of determined pseudorandom noise codes reaches a cardinal number of the set of spreading code, which is to be created.
EFFECT: higher efficiency of using an available pass band by creation of a spreading code with improved cross correlation properties of codes.
