A class of transformations that polarize binary-input memoryless channels
Satish Babu Korada, Eren Şaşoğlu · 2009
A generalization of Arıkan's polar code construction using transformations of the form G⊗nwhere G is an ℓ × ℓ matrix is considered. Necessary and sufficient conditions are given for these transformations to ensure channel polarization. It is shown that a large class of such transformations polarize binary-input memoryless channels.
