Computing Free Distances of Idempotent Convolutional Codes
José Gómez-Torrecillas, F. J. Lobillo, Gabriel Navaro · 2018
We show that, for cyclic convolutional codes, it is possible to compute a sequence of positive integers, called cyclic column distances, which presents a more regular behavior than the classical column distances sequence. We then design an algorithm for the computation of the free distance based on the calculation of this cyclic column distances sequence.
