Random pulse train spectrum calculation unleashed

In this investigation we suggest a novel solution to a problem in spectrum analysis - the spectrum calculation for binary pulse amplitude modulated non-return to zero signals with non-uniform duration of symbol intervals. The usefulness of the developed theory is demonstrated by the one important random pulses train case. The validation of the analytical approach derives from the coincidence of spectrums received by simulation and calculation. Eventually, one more problem, which was defined as unsolved in the literature [1 - 3], is marked as solved, which opens new horizons for further spectrum analysis theory developments.
