CALCULATION OF DIGITAL ELECTRICAL SIGNALS SPECTRUM
Abstract
In communications technology for testing of digital channels and links are widely used digital signals with fixed and pseudorandom structures. The author proposes a method for simulating and analyzing the characteristics of the power spectral density of standard test digital electrical signals for different methods of linear coding. As models of their initial (primary) formations are used standard binary sequences of fixed and pseudorandom structures. As an analytical tool the method is suitable for studying the effect of the linear coding and modulation formats on the quality of data transmission in high-speed networks of transport links.
