You can do so by adding FSK Modulator, FSK Demodulator and a BER analyzer block in your model.

Remember to configure the FSK blocks according to parameters relevant to your model.

Connect the output of the FSK Modulator to the input of the FSK Demodulator block.

Then connect the output of the FSK Demodulator to the input of the BER Analyzer block.

After the simulation completes, you can analyze the results using the available scopes or sinks in Simulink, or you can extract the data and plot the BER, Doppler shift, and SNR graphs using MATLAB functions. The BER Analyzer block provides the BER results, which you can observe in the Simulink output.

Hope this helps.
