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), Arıkan 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 polarization-adjusted convolutional (PAC) codes. WebWith our proposed metric function, the PAC codes' decoding computation is comparable to the conventional convolutional codes (CC) sequential decoding. Moreover, simulation …
