Abstract
Construction of new codes by modifying (extending, puncturing, etc) a known code is a practice common when dealing with classical codes. We have shown in this paper that good codes can be obtained with these techniques, apparently not effective for fountain codes. Lengthened Luby Transform Codes have being demonstrated, trough simulation, to perform better when compared to the mother codes, under the same redundancy condition. Lengthening might be a useful technique which alleviates the need for large frame requirements posed by the fountain codes.
