Thanks Steve, Yes I'm still bring the C code up to the latest Octave version. Haven't decided on the extact bit rate (and number of carriers yet). This is a diversity waveform, top 4 carriers have the same information as the bottom four. Demod puts them back together. Gives 4dB gain for fading channels.
