I think the matrix is only generated once for inspecting its performance and after testing hardcoded into the final program. Just discovered that the encode and decode program from http://radfordneal.github.com/LDPC-codes/progs.html support named pipes. May be a chain like c2enc | encode | gmskmodem_mod | gmskmodem_demod | decode | c2dec is possible out of the box...
