Hello Marco, rest assured that with 3MS/s you can bring a fully fledged workstation to a constant boil, if you just do the wrong things on it. For example: you might want to receive ham radio. Ham radio often needs to squeeze the best SNR out of your signal; that usually requires great filters. Now, the better (read: steeper) your FIR filter is, the longer it gets [1], so try doing a 200Hz transition width low pass on a 2MHz nyquist band (hint: it get's ugly. Without multirate filters, that would easily be 133GFlop/s [ripple=1e-3=delta_stopband]).
Now, we all love gr-ieee802-11, so why not point [2] you at it? Greetings, Marcus [1] N_filt ~= 2/3 log10(1/(10*ripple_passband*delta_stopband)) * f_nyquist/f_transition On 02/06/2015 07:48 PM, 2_...@libero.it wrote: > Hello, > I've only a TV tuner E4000 for have fun with gnuradio..unlucky its > sample rate is less than 3MSPS..I want to have fun with application > more compute intensive, in order to see better bottlenecks and latencies.. > Could you tell me where I can find(if they exist) files with sample of > 802.11 transmission, or other heavy application? > > Thank you, > marco > > > _______________________________________________ > Discuss-gnuradio mailing list > Discuss-gnuradio@gnu.org > https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
