On the metric and computation of pac codes
Web17 de fev. de 2024 · In the Shannon lecture at the 2024 International Symposium on Information Theory (ISIT), Ar {\i}kan proposed to employ a one-to-one convolutional transform as a pre-coding step before polar transform. The resulting codes of this concatenation are called {\em polarization-adjusted convolutional (PAC) codes}.

Web10 de jul. de 2024 · Thus, list VA results in a significant reduction in the latency of the decoding. For instance, for list decoding of PAC (256,128) with m=6 and L=128 which has 128 survivors at each decoding stage, the total number of sorting stages throughout decoding is KΨLD=128×36=4608. Web17 de nov. de 2024 · This letter proposes a new construction for PAC codes based on a weighted sum (WS) metric, which considers both the cutoff rates and the utilizations of the polarized subchannels, and shows the designed codes can outperform the ones that are designed by the existing techniques. 1 View 1 excerpt, cites background
