Group convolutional codes
Sergio Estrada, Juan Ramón García Rozas, Justo Peralta, E. Sánchez-García · Advances in Mathematics of Communications · 2008
In this note we introduce the concept of group convolutional code in terms of skew polynomial rings. Then we use some theorems due to Jategaonkar that describe such rings in terms of matrices to characterize minimal $S_3$-convolutional codes over the field of five elements.
