Matlab code Give the user the option to choose the generation of one of the following four spreading codes: Barker code, M-sequence, Gold code or Walsh code

1. Give the user the option to choose the generation of one of the following four spreading codes: Barker code, M-sequence, Gold code or Walsh code. 2. Plot the chosen code as a function of time, 3. Plot the ACF (Auto Correlation Function) of the chosen code. 4. Plot the PSD (Power Spectral Density) of the chosen code. 5. Output the Processing Gain (PG) of the chosen code.
