RESUMO

Thls research reports studies on Superlinear Periodically Time Varying Trellis Coded Modulation resulting from an interleavlng approach of Time Invarlant Trellis Coded Modulation. The performance of some of these schemes under the asymtoptlc coding gain as well as comparisons with the previous time invarlant ones are presented. The codlng and decodlng processes, the way the combinations are performed, the structure and characteristics as well as an analysis of the unequal error protection provided by these TCM codes are presented. Finally, the advantages and disadvantages of these new schemes are part of the conclusion as are the suggestions for future research
