Fast Methods for Ranking Synthetic BECs

Hsin-Po Wang, Vlad-Florin Drăgoi

We gather existing methods that are used to compare and rank the BECs synthesized by a polar code constructor, compare them, and propose new methods that compare synthetic BECs fas…

Density Devolution for Ordering Synthetic Channels

Hsin-Po Wang, Chi-Wei Chin

Constructing a polar code is all about selecting a subset of rows from a Kronecker power of $[_{1}^{1}_{1}^{0}]$ . It is known that, under successive cancellation decoder, some rows are P…

Optimal Self-Dual Inequalities to Order Polarized BECs

Ting-Chun Lin, Hsin-Po Wang

$1 - (1 - x^{M})^{2^{M}} > (1 - (1 - x)^{M})^{2^{M}}$ is proved for all $x \in [0, 1]$ and all $M > 1$ . This confirms a conjecture about polar code, made by Wu and Siegel in 2019, that $W^{0…
