| Abstract: |
| In this paper, we discussed the modulation techniques for combining turbo code with TCM. We gave three modulation schemes, and we compared these schemes . In the end, we simulated three schemes by using computer, proved that its performance is better, than the TCM by using convolu tional codes. |
