My name is Johannes Demel and I am a Master degree student at *Karlsruhe Institute of Technology (KIT)*. +Basics +---------- +The project is based on Erdal Arikan's 2009 paper *Channel Polarization: A Method for Constructing Capacity-Achieving Codes for Symmetric Binary-Input Memoryless Channels*. An in-depth explanation of my project is given in my project proposal <https://github.com/jdemel/socis-proposal>. -Please see http://gnuradio.org for the wiki, bug tracking, -and source code viewer. +Structure +---------- +The aim of the project is to add POLAR code encoder, decoder, channel construction capabilities to GNU Radio. POLAR codes are used for channel coding, thus all files shall reside within the *gr-fec* submodule. Also encoder and decoder shall use the FECAPI. The decision to do all development in-tree is driven by previous experience that out-of-tree modules are often terribly hard to merge later on and it may take years to do so. -If you've got questions about GNU Radio, please subscribe to the -discuss-gnuradio mailing list and post your questions there. -http://gnuradio.org/redmine/projects/gnuradio/wiki/MailingLists +Project +------- +A quick overview of my project timeline goes as follows. -There is also a "Build Guide" in the wiki that contains OS specific -recommendations: -http://gnuradio.org/redmine/projects/gnuradio/wiki/BuildGuide - - -The bleeding edge code can be found in our git repository at -http://gnuradio.org/git/gnuradio.git/.
