ETSI DVB-T Compliant OFDM Dumps

Hi Fellow GNURadioers,

due to a rather relevant number of requests, as well as while
apologizing
for some delay in doing this,
I’m re-posting to this list a few links to resources regarding GPP-SDR
implemented DVB-T systems.

ETSI DVB-T I/Q BASEBAND DUMP (2048k, 1/4, 16-QAM, 2/3, 11.612Mbps net
bitrate)

www.pellegrini-radio.it/ing/ofdm_40.dump (1 single RAI -
RAdiotelevisione
Italiana ch. + stuffing)
www.pellegrini-radio.it/ing/ofdm_4ch.dump (4 ch, available in a few
hours
from now)

Youtube demo videos:

GPP-SDR implemented DVB-T Modulator over 2.5-Watts Atom N270

GPP-SDR implemented DVB-T DeModulator


GPP-SDR implemented DVB-T SFN

regards to everybody

Jeremy those shorts are little endian indeed, I guess Vincenzo is
using a little endian
architecture machine and while dumping those he didn’t use htons,
while in principle this
is not required, let’s say it’s a kind thing to do just to avoid
headache dealing with
heterogeneous systems.

As side note C++ standard doesn’t state how to store primitive types in
memory,
and for the matter even for not primitive types (think about the
position of virtual table
pointer) it is not defined but just compiler dependend.

Gaetano M.
