摘    要:DVB—T是最近十年全球地面数字电视传输系统使用最广泛的一种标准,本文通过分析相位噪声对DVB—T传输系统的影响,提出了两种适用于该系统且易于硬件实现的CPE(公共相差)均衡方法,并比较了它们的实现复杂度。仿真表明,在多径衰落条件下,两种方法均提高了系统性能。

关 键 词:数字视频地面广播(DVB—T)  正交频分复用(OFDM)  相位噪声  CPE

Abstract:During the present decade, DVB-T has been the most widely-used standard for digital terrestrial television in the world. This paper analyzes phase noise effects on the performance of DVB-T system and presents two methods of the CPE (common phase error) equalization which adapted to the DVB-T system and are easy to be implemented with hardware. Simulation results show that the methods are very effective, especially in fading channels.
Keywords:Digital Video Broadcasting-Terrestrial (DVB-T)  Orthogonal Frequency Division Multiplexing (OFDM)  phase noise  CPE
