lbb123 commented 6 years ago

As I kown,the CDMA system use multi-carrier modulation but I didn't see multifrequency carrier?it that in usrp?

anastas commented 6 years ago

CDMA has nothing to do with multi-carrier! They are two different transmission schemes. You can use multi-carrier in CDMA but this is not a component of CDMA.

In your mean,CDMA just process the baseband signal?What difference about the MC-CDMA,CDMA2000 in 3G and this system?

This is not a good place for you to learn what CDMA is. If you want to get an idea start here: https://en.wikipedia.org/wiki/Code-division_multiple_access

All my code is open source and sufficiently documented. If you want to see what I am doing all you have to do is read it! Let me know if you have any questions on my project.
