-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hey all,
GSoC14 is coming to an end. So one final update before the "pencils down" date. Max-Log-Map decoder is finished. Code is available on my Github[1]. More Info in my blog[2]. So now it is time for code cleanup and documentation. GSoC14 was fun and I'm looking forward to GRCON now :) Best - -Jan [1] https://github.com/spectrejan [2] http://spectrejan.blogspot.de/ On 16.07.2014 13:51, Jan Krämer wrote: > Hey all, > > I have some updates for you too.
