It really helped me in understanding the theory.

This is a great baseline that I used as a starting point for creating a spread spectrum simulation.

Parallel to serial converter needs work. I know thatI and Q are complex but wanted to see if it could be done with real values and not use phase demapping. It's close, but not good enough. I will keep working with it.
