Annotations languages:

The article is devoted to the further investigation of the spectral properties of codewords of generalized cascaded codes. Analysis of the known approaches to the description of the spectral properties and the study of structural and algebraic properties of the simplest cascade code designs showed that the use of multidimensional spectra is the most apt to describe. The authors propose a mathematical tool that allows you to examine the spectral properties of generalized cascaded codes.
Keywords: generalized cascaded code, the spectral properties of codes, multidimensional spectra, Fourier transform
