NAME

       polar_channel_construction - Gnu Radio Polar Configurator

DESCRIPTION

       POLAR code channel construction.

Channel Construction

       polar_channel_construction exposes functionality to calculate polar channels for different
       sizes.  It may be used to calculate Bhattacharyya parameters once and store them in a file
       in '~/.gnuradio/polar'.  Frozen bit positions are recalculated on every run.

       polar_channel_construction   provides   a  command-line  interface  for  all  the  channel
       construction code.  These features are also accessible via the Polar Configurator block in
       GRC.

BEC

       BEC channel construction can be calculated explicitly because the BEC represents a special
       case which simplifies the task.  All functionality regarding this channel  is  located  in
       'channel_construction_bec'.

AWGN

       In  general  channel  construction for polar codes is a very time consuming task.  Tal and
       Vardy proposed a quantization algorithm for channel construction which makes it  feasible.
       The  corresponding implementation is located in 'channel_construction_awgn'.  It should be
       noted that this more of a baseline implementation which lacks all  the  advanced  features
       the  original  implementation  provides.   However,  simulations  show  that  BEC  channel
       construction with a design-SNR of 0.0dB yields similar performance and should be preferred
       here.
