Abstract
Presents the first twelve weight spectra of some optimal, rate 1/2 to 1/8, convolutional codes with constraint lengths from 3 to 8. The main task is accomplished by using the software MAPLE to solve sets of symbolic equations. In particular, the results for code rate 1/2, 1/3 and 1/4 match to those available in the literature. The data obtained can be utilized to upper-bound the performance of a convolutionally coded system which uses the Viterbi algorithm for either soft-decision or hard-decision decoding
