All,

 

I’m interested in, and looking into the Pi/4 QPSK modulation technique (http://en.wikipedia.org/wiki/Phase-shift_keying#.CF.80_.2F4.E2.80.93QPSK).

 

Has anyone worked on this before and does anyone have any blocks or code that I could use for reference while making my own? Any help, links, blocks or code would be greatly appreciated!

 

Thanks,

Luke
