The Chen-Mobius multi-carriers digital communication system and its simulation

The results of Chen-Mobius transform of some often-used waveforms were applied in the digital communication systems. In addition to modern digital communication systems, the new coherent modulation-demodulation systems by two classes of the oblique-orthogonal function set were applied to the communication systems. Then the new Chen-Mobius multi-carriers digital communication system was simulated by the MATALAB and the systems´ figures of its error rate to different ratio of S/N and by different function set were given and analyzed. Compared with the traditional system the results showed that the new system has excellent performances to resist the strong noise and interference and the reasons of which were discussed in some detail.
