Hi, I am using Simulink to simulate Direct Sequence Spread Sprectrum. But I am not sure how to observe the output and semilog graph for bit error ratio vs. signal-to-noise ratio. Would really appreciate any kind of answers and help. Thank you! (I have also included the Simulink file of the DSSS)

I understand that you want to observe the output frequency and plot a semilog graph for bit error ratio vs Signal to noise ratio.
The "Spectrum Analyzer" Simulink block can be used to display frequency-domain signals and the frequency spectrum of time-domain signals. "semilogx" MATLAB function can be used to plot a semilog graph. Please refer to the below documentation to know about bit error rate and Signal to noise ratio.
You may also refer to below documentation to know more about "Spectrum Analyzer" Simulink block and "semilogx" MATLAB function.
