[Discuss-gnuradio] isdb-t implementation in gnuradio

[Federico Larroca]

Hi everyone,

Here in the lab we have been working for several months with USRPs and GNURadio, both for teaching and research, but specially the former. Students are very very motivated by the sense of reality that they bring. All in all, congratulations for all the developers involved.

In any case, here in Uruguay they are starting to deploy digital TV, the ISDB standard in particular. So we figured that a good "long-term" project would be to implement an ISDB receiver. The first thing we had done is to verify if anyone has developed (or at least started to develop) such receiver with GNURadio and USRP (or any other SDR platform, such as BladeRF).

After conducting a realtively thorough search on the internet, we have concluded that some work has been carried out, but no code has been made public. In particular, we found the following related works:

 - The work of the group of Vincenzo Pellegrini in DVB, which is not available (https://www.ruby-forum.com/topic/1440970).

 - Receiving only the 1seg by a group in the Nara Institute of Science and Technology, which I believe is not available either (a demo in youtube: http://www.youtube.com/watch?v=svzMwFrcNC0).

 - A paper by a group in the University of Campinas (Brazil), where they report of an ongoing work to implement a ISDB-T transmitter (see http://groups.winnforum.org/europe_papers_wednesday#2.3), but of which I could not find anything except the paper.

Anyone knows of a project to implement such receiver in GNURadio? Or maybe someone has tried and concluded that the required computation is too much for the host PC?

Thanks in advance.

Best regards,
Federico
