In both cases, if the linear block code is systematic, then the resulting convolutional encoder is systematic, minimal, basic and non-catastrophic. The Hamming free distance of the convolutional code is bounded below by the minimum Hamming distance of the block code. New examples of binary convolutional codes that meet the Heller upper bound for systematic codes are given.}, journal = {International Journal of Mathematical and Computational Sciences}, volume = {6}, number = {11}, year = {2012}, pages = {1481 - 1484}, ee = {https://publications.waset.org/pdf/9501}, url = {https://publications.waset.org/vol/71}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 71, 2012}, }
