PROGRAM:
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.
