Abstract
A new method is proposed for generation of pseudo-noise signals. The method uses M-sequences with non-multiple recurring periods. Results of mathematical simulation of correlation and spectral characteristics of combined sequences are presented, comparison with Gold sequences is performed. The influence of the number of characters and the clock frequency of the original sequences on the characteristics of the combined sequences is studied. The histograms of distribution of side lobes levels for different combinations of number of characters and the clock frequency of the original sequences are presented.

Keywords: pseudorandom sequences, equivalent linear complexity, correlation characteristics, spectral characteristics, mathematical number theory
