DESCRIPTION

9       POLAR code channel construction.
10

Channel Construction

12       polar_channel_construction  exposes  functionality  to  calculate polar
13       channels for different sizes.   It  may  be  used  to  calculate  Bhat‐
14       tacharyya  parameters once and store them in a file in '~/.gnuradio/po‐
15       lar'.  Frozen bit positions are recalculated on every run.
16
17       polar_channel_construction provides a command-line  interface  for  all
18       the  channel construction code.  These features are also accessible via
19       the Polar Configurator block in GRC.

BEC

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

AWGN

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