地面数字电视广播传输标准SMCC+系统的关键技术

Key Technology of Digital Terrestrial TV Broadcasting Transmission Standard SMCC+ System

描述了由电子科技大学提出的地面数字电视广播传输标准SMCC+(SynchronizedMulti-Car rierCDMAplus)系统。通过与现有的地面数字电视广播(DigitalTelevisionTerrestrialBroadcasting)标准在调制方式、同步、信道估计、相噪技术、峰平比、编码等方面的比较,证明了SMCC+系统具有比现有的标准更优越的性能。

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.
