✦ Synopsis

The minimum free distance of a convolutional code is the most important factor affecting its error correcting capability. An easy to implement, systematic method for computing the minimum free distance is presented. The computer search is minimized by first excluding catastrophic codes, then applying a matrix technique on different code patterns to locate the best codes.
