The latest release of the communications package is from 2015-04-04.
(crucially needed) modification of the qammod/qamdemod files with
Gray coding. This patch seems to be from June 2016 and it hasn't found
its way into the package. True? Is there any way to implement it, as
without Gray coding these modulators are of limited use.
I already tried to contact the maintainer, but did not get an answer yet.
Thanks in avance.
