Hi Achilleas, sorry for the belated reply but I was very busy working on extending MA over SR-DVB and with other academic stuff here. MA actually stands for "Memory Acceleration" and is intended as an optimization technique aimed at signal-processing-generated computation over GPPs and DSPs (we h

Hi Per, carrier freq is 809.5 MHz (one of the Australian DVB-T center freqs in UHF) Phase and frequency responses are compensated by applying estimations done based on the (many) DVB-T OFDM pilot carriers. We do not average channel estimates to remove noise, still we get very clean constellation w

Yes Dave, it is absolutely safe. Actually going from DVB-T to DVB-S (version 1), roughly speaking, only requires removing some OFDM-related blocks, which means it makes the system computationally lighter.. :) Hi Alexander, Yes, I absolutely want to share MA-related knowledge with the software ra

Hi Vincenzo, That's interesting. Can you point to some description or this "MAgic" technology? From your description I'm not sure I understand even on what level it works and what it actually does :) On Fri, Jan 29, 2010 at 12:04, Vincenzo Pellegrini wrote: > Hi GNURadio fellows, > considering t

Wow this is exciting! Folks we are on the verge of a paradime shift in RF communications. I'm not clear on the dvb standards, but is it safe to assume dvb-s would need just a few tweaks on the dvb-t code or no? Sent from my iPhone On Jan 29, 2010, at 4:04 AM, Vincenzo Pellegrini wrote: Hi
