Advantage of using permutation trellis codes and M-FSK modulation for power-line communications channel

The technique of Distance-Preserving Mappings (DPM) which maps the outputs of convolutional codes onto permutation sequences has shown interesting application in powerline communication channel. The M-FSK modulation scheme has also shown its robustness when used for hostile channel as the power line channel. The Combination of Distance-preserving mappings and M-FSK modulation scheme, achieves good results when applied for narrowband interference. A simulation analysis of the importance of these two techniques is discussed and presented in this paper. The obtained results have shows the benefit and the advantage of the use of both techniques.
