A Comparison of Distance Bounds for Quasi-Twisted Codes

2021 · IEEE Transactions on Information Theory

Spectral bounds on the minimum distance of quasi-twisted codes over finite fields are proposed, based on eigenvalues of polynomial matrices and the corresponding eigenspaces. They generalize the Semenov-Trifonov and Zeh-Ling bounds in a way similar …
