softDVB-T Project

... development of Software Defined modulator for Terristial Digital Video Broadcasting (DVB-T), necessary for verification purposes of receivers

Work status

Development was partitioned to stages according block diagram found in ETSI EN 300 744:

Block's name status behavioral model (perl)
Energy Dispersal published energy_dispersal.pl
Outer Coder published reed-solomon.pl

Source files and repository

Full set of source files is available in public repository on sourceforge.net portal. If you want download project, install SVN and type from command line:

svn co https://softdvb-t.svn.sourceforge.net/svnroot/softdvb-t softdvb-t

Downloaded directory 'gr-dvb-t' should be placed directly in GNU Radio root directory ($gr_source_path/gnuradio-3.3.0/gr-dvb-t), then you should change to this directory and type:

./bootstrap
./configure
make
make check
sudo make install

Now you can use our modules both in text-mode (Python's script) as in graphic mode (gnuradio-companion).
