How do you simulate the modulation for the ADS-B For a simulation?

I know there are different modulations for ADS-B. I was wondering how I would use MATLAB to simulate them. They are DSPK, QPSK and PPM modulations . The Center frequency is 1090 MHz. Any thoughts?

Hi @Michael Thompson,

It's possible to simulate DPSK and QPSK using the “pskmod” function from the “Communications Toolbox”. Please refer to the documentation below:

For generating PPM modulation, please use this MATLAB answer as a reference:
