On the Rate of Channel Polarization
Abstract
Description
It is shown that for any binary-input discrete memoryless channel $W$ with symmetric capacity $I(W)$ and any rate $R <I(W)$, the probability of block decoding error for polar coding under successive cancellation decoding satisfies $P_e \le 2^{-N^β}$ for any $β<\frac12$ when the block-length $N$ is large enough.
