All the software, including the documentation you are viewing here, is contained in a Unix tar file, which you can download by clicking one of the options below:
Tar file of LDPC software (0.9 Megabytes)
Gzipped tar file of LDPC software (0.4 Megabytes)
Once you obtain the tar file (and uncompress it with gunzip if necessary), you should extract the files with the following Unix command:
This will create a directory called LDPC-2001-05-04, and place all the source, documentation, and other files in this directory.tar xf LDPC-2001-05-04.tar
If you prefer for this directory to be called something else, rename it now, before compiling the programs, since the file randfile in this directory, containing natural random numbers, is accessed according to its path when the programs were compiled.
Once the tar command above has finished, you should change into the newly-created directory, and type
If all goes well, this should compile all the programs (except for some test programs).make
The sub-directory bin contains symbolic links to all these programs. You might want to place it in the PATH variable used by your shell to find programs.
The LDPC directory contains a copy of all the HTML files documenting the software, such as the one you are reading now, with the file index.html being the starting point. I recommended that you use this local copy when referring to the documentation, rather than get it from my web page. Just tell your browser to open the URL
where path-to-software is the full path (starting with "/") to the directory where you've put the software.file:path-to-software/index.html
will remove all the compiled programs, as well as the files created when the examples are run.make clean
