Some months ago we started working on an ISDB-T receiver for GNU Radio. We have reached a point at which it may be useful for other people, so we decided to announce to it on the list. The sources may be found on: https://github.com/git-artes/gr-isdbt
Although this is an ongoing work, the receiver is now capable of roughly two things (examples included):
- Synchronize to the OFDM symbol, equalize, and decode the TMCC signal (equivalent to the DVB's TPS). This has been tested for mode-3 transmission (i.e. 8k OFDM) and several CP lengths, which is what we have available here, but it should work with all the modes and CPs.
- Display online the 1-segment video (i.e. the low definition portion that is generally sent in ISDB-T). Again, this has been tested with the transmissions available here in Uruguay.
