Arikan polar codes
Arıkan briefly served as a tenure-track assistant professor at the University of Illinois at Urbana-Champaign. He joined Bilkent University as a faculty member in 1987. In 2008 Arıkan improved the implementation of polar codes, a system of coding that provides a mathematical basis for the solution of Shannon's channel capacity problem. A three-session lecture on the matter given in January 2015 at Simons Institute's Information Theory Boot Camp … Web17 feb 2024 · In the Shannon lecture at the 2024 International Symposium on Information Theory (ISIT), Arıkan proposed to employ a one-to-one convolutional transform as a pre-coding step before the polar transform. The resulting codes of this concatenation are called polarization-adjusted convolutional (PAC) codes. In this scheme, a pair of polar …

The code construction is based on a multiple recursive concatenation of a short kernel code which transforms the physical channel into virtual outer channels. When the number of recursions becomes large, the virtual channels tend to either have high reliability or low reliability (in other words, they polarize or become sparse), and the data bits are allocated to the most reliable channels. It is the first cod… law and order organized crime pearl
