[Discuss-gnuradio] DVB-T Modulation over low-end ATOM CPU

[Vincenzo Pellegrini]

Hi fellow GNURadioers,

just in case somebody is interested, this is the main dish of our SDR demo, which we will be presenting within GLOBECOM 2010 (Miami, FL) demo session on Dec. 8th.  Title of the demo is "Showcasing MA potential", as it aims to provide a glimpse of computational performance results that one might have by applying the programming technique described in http://www.pellegrini-radio.it/MA/ to an SDR system.

The video proves real-time, live ETSI DVB-T modulation for 4 standard resolution channels (11.612 Mbps useful protected bitrate) to be possible

.:. over an Intel ATOM N270 CPU  

.:. which consumes 2.5 Watts of electrical power

.:. by requiring less than 70 % of its computational power

with nothing but C++ code and MA technique involved.

We believe there is still margin for application of the MA technique, compuational cost can be further reduced.

Of course, not comparable to the power efficiency of an ASIC. Yet.

regards to everybody

vince
