Simulink resources of the MATLAB environment were used to simulate and investigate the system efficiency. A transmitter, a receiver, and a channel were developed. The model study was conducted at low and high noise levels. Also, the spectra of the received and received signals were taken, the signal constellations were plotted on the plane and the BER vs SNR was built. The result of the work done shows how you can build a reliable signal modulation scheme that is resistant to electromagnetic interference.
