Power spectrum analysis of pseudo-random pulses sequence

This article demonstrates the analysis of power spectrum by applying a channel code with ranged pulses sequence. The models types taken for this analysis represent a “raised cosine” type and a rectangular pulses type. The study shows that the application of the code 8b/10b makes it possible to limit the spectrum of the signal in the zero-frequency area. The article contains the results of applying the developed analytical method as well as mathematical modeling towards the power spectrum of the signals concerned.
