| Abstract: |
| Synchronized Multi-Carrier CDMA plus (SMCC +) system, proposed by University of Electronic Science and Technology of China, is described. Compared with the existing standards of the Digital Television Terrestrial Broadcasting (DTTB) in modulation, synchronization, channel estimation, phase noise, peak to average peak ratio (PAPR) and code, etc, SMCC+ system has better performance than those of the existing standards. |
