I misunderstood your original message. I thought you said that your code used the methode as used by the BeRT arduino application to decode two streams at a time.
I did a litle bit of research and the atmega does have a 8-by-8-multiply it can do in hardware in just two clock-cycli so that is indeed quite fast; much faster then I thought.
I'll give this a try tomorrow.
On the other hand, I'm still interested to understand how the algorithm used in the BeRT application application actually works. Perhaps the best way will be to implement it and run it on a demo audio-file.
(For some reason, gnuradio companion crashes on me on my ubuntu 14.04 box. It did work before but now not anymore! Grr!!!
