After describing the basic concepts and technical features of single-carrier and multi-carrier systems, this paper analyzes and compares the performances of the two schemes against Doppler spread, Multi-path spread and Error propagation in DTTB mobile reception environment.
介绍了单载波和多载波系统的基本概念和技术特点,分析和比较了这两种制式在地面数字电视广播移动接收中抵抗多普勒扩展、多径扩展及误码扩散的性能,并对比了ATSC和DVB-T标准的移动接收实验测试结果。
The development of the Digital Television Terrestrial Broadcasting (DTTB) and channel characters of the DTTB are first described in this paper,and the channel estimation method for the DMB-T (Terrestrial Digital Multimedia/Television Broadcasting) standard innovated by Digital TV R&D Center of Tsinghua University is then discussed in details.
本文在简介地面数字电视广播（Digital Television Terrestrial Broadcasting,DTTB的发展及其信道特点的基础上,描述了国外现有的DTTB传输标准和清华大学数字电视传输技术研发中心提出的DMB-T（Terrestrial Digital Multi-media Television Broadcasing）所采用的信道估计算法,并对以上信道估计性能进行比较,证明DMB-T信道估计算法受高斯噪声和时变信道估计的影响更小,而且算法实现更简单。

With the background of the National Standard for DTTB, we propose a time-domain adaptive cancellation method which is achieved by analyzing the PN sequence in the received TDS-OFDM signal to obtain an estimation of the impulse response of the coupling channel, and then using the estimation result to generate a feedback signal to cancel the echo.
