Abstract

In this paper we give a self-contained overview of known distance measures for convolutional codes and of upper and lower bounds on the free distance. The upper bounds are valid for general trellis codes and for convolutional codes, respectively. The lower bound is valid for time-varying convolutional codes. We also present a new lower bound on the distance profile for fixed convolutional codes.
