Hi William,
nice to hear that you appreciate the work.

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.

Regards

vince
