The paper discusses the correlation properties of pseudo-random sequences (PRS) used to form noise-like signals in high-speed data transmission systems. The most frequently used pseudo-random sequences are considered: modified Barker codes, M-sequences having the same length. In the MatLab a comparative analysis of the correlation properties of the PRS. It is shown, that modified Barker codes have unsatisfactory correlation properties. It is shown, that the use of M - sequences allows to obtain signals with the required correlation properties for communication systems, including for systems with code division of channels. The directions of further research are determined. |
