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 P. in DVB, which is not  
available ([DVB-T software for USRP? - GNU Radio - Ruby-Forum](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:  
[Decoding 1seg using software decoder on Linux PC with USRP2 (GNU Radio). (English version) - 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](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
