A new structured design method for convolutions over finite fields, Part I

Finally, our approach was heavily based on the use of Shannon-Fan0 codes, and not on the optimal Huffman codes. The problem is much more involved and challenging when Huffman codes are considered. Pioneering work on this difficult problem has been performed by Longo [ 181, [19], Nemetz and Simon [20], [21]. In the papers of Longo [ 181, [ 191 the informational divergence H(P IlQ) plays an important role in the problem. ACKNOWLEDGMENT I wish to thank the reviewers for pointing ships to previous work and for providing comments.
