| 中文摘要: |
| 介绍了基于导频的数字高清晰度电视地面广播系统的COFDM解调同步实现方案.以多载波调制的同步接收理论为基础,重点对COFDM接收方案中的频率偏移、符号定时恢复和采样钟偏移估计进行了原理分析. |
| 英文摘要: |
| This paper introduces how the OFDM system transmits the terrestrial HDTV signal to complete synchronization through pilots. Basing on the theory about synchronization of multi-carrier modulation system. This paper explains how to realize the timing recovery and estimation of the offset of frequency and sample. |
