POLAR_CHANNEL_CONSTRUCTION(1) User Commands POLAR_CHANNEL_CONSTRUCTION(1) NAME polar_channel_construction - Gnu Radio Polar Configurator DESCRIPTION POLAR code channel construction. Channel Construction polar_channel_construction exposes functionality to calculate polar chan- nels for different sizes. It may be used to calculate Bhattacharyya para- meters 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 Po- lar Configurator block in GRC. BEC BEC channel construction can be calculated explicitly because the BEC rep- resents a special case which simplifies the task. All functionality re- garding 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 con- struction which makes it feasible. The corresponding implementation is lo- cated in 'channel_construction_awgn'. It should be noted that this more of a baseline implementation which lacks all the advanced features the origi- nal implementation provides. However, simulations show that BEC channel construction with a design-SNR of 0.0dB yields similar performance and should be preferred here.
