A Simple Proof of Polarization and Polarization for Non-Stationary Memoryless Channels
Mine Alsan, Emre Telatar · IEEE Transactions on Information Theory · 2016
We give a simple proof of Arıkan's polarization phenomenon that uses only elementary methods. Using the same method, we show that Arıkan's construction also polarizes non-stationary memoryless channels in the same way it polarizes the stationary memoryless channels.
