RESUMO

Alternative coding techniques for high speed optical transmission systems, in wich the use of extensive tables in memory is a problem, have been discussed in recent literature. Two solutions for this problem are discussed in this work. The first is a modified version of the PFmB(m+ 1)B codes, with higher performance and no added complexity. The second coding method combines traditional codeword assignment techniques with algorithmic techniques. This method minimizes the size of the tables for the specified running digital sum. The compromise between the table size and sequence imbalance is studied and dimensioned. Finally, other performance parameters such as spectral properties, synchronizability, and error rate monitorizability, are studied
