ISDB-T Modulation?

GNU Radio
1

I am aware that ATSC, and various forms of DVB-T/2 modulators exist in
GNURadio both with standard and custom blocks; but is there any active
development or possibility of ISDB-T modulation? What exactly would need
to
be done in order to achieve it? It doesn’t seem all-too different from
DVB-T in the sense that it wouldn’t be a from-scratch effort.

Thanks in advance.

Hi Jordan,
I live in Brazil and I always tried to find efforts developing an ISDB-T
modulator, but never find it.
Of course it’ll not be a from-scratch effort, as some blocks are already
in gnuradio.

Best regards,

Hi Jordan,

I remember a group from Brasil presenting a ISDB-T modulator implemented
in gnuradio when I attended wireless innovation forum in 2012. The
presentation is here:
http://groups.winnforum.org/europe_papers_wednesday#2.3, A Software
Defined Radio Approach for Digital Television ISDB-T Transmitters. The
project was done by the university for the government to evaluate the
standard. Some months ago I was looking for sourcecode and I realized
that it was not released to the public.

ISDB-T should not be hard to implement except few modules which are
specific, among them being the Band Segmented OFDM.

Regards,

Bogdan
