Comparison of the process of forming orthogonal code-frequency modulation and angular modulation in the Matlab Simulink

Gumarov Andrey Rashitovich

In the article, the model of generators for building: a frequency-modulated signal, a phase-modulated signal, an orthogonal code-frequency modulated signal, in the Matlab Simulink software package. The process of forming an orthogonal code-frequency signal is considered, a comparison is made with frequency and phase modulation. The key difference with orthogonal frequency code modulation is the increase in frequency over time, as a consequence of the expansion of the parameter signal.

Keywords:orthogonal code-frequency modulation (OCFM), angular modulation, frequency modulation (FM), phase modulation (FM), frequency, phase, Matlab, Simulink.
