Venkatesan Guruswami, Andrii Riazanov, Min Ye#### Ar?kan meets Shannon: Polar codes with near-optimal convergence to channel capacity

Revisions: 3

Venkatesan Guruswami, Andrii Riazanov, Min Ye

Let $W$ be a binary-input memoryless symmetric (BMS) channel with Shannon capacity $I(W)$ and fix any $\alpha > 0$. We construct, for any sufficiently small $\delta > 0$, binary linear codes of block length $O(1/\delta^{2+\alpha})$ and rate $I(W)-\delta$ that enable reliable communication on $W$ with quasi-linear time encoding and decoding. ... more >>>
