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.
