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.
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'.
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.
