Hi William, nice to hear that you appreciate the work. http://www.youtube.com/watch?v=S5nGBDCxhmk Here you can see what happened when we applied MA to our ETSI DVB-T demodulator earlier this year. We demoed this at WSR10, Karlsruhe, Germany. Since then, we increased the amount of MA within the receiver chain, which yielded major computational performance improvements.
The dream that we're aiming for is to be able to provide some sort of MA compiler which can automatically implement an SDR including as much as possible of the MA computational benefits, once given a high level C++ description of the radio chain.
