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.
