Abstract :
A method to polarize channels universally is introduced. The method is based on combining two distinct channels in each polarization step as opposed to Arikan´s original method of combining identical channels. This creates an equal number of only two types of channels, one of which becomes progressively better as the other becomes worse. The locations of the good channels are independent of the underlying channel, guaranteeing universality at rate 1/2. The method is generalized to construct codes of arbitrary rates.
