Symbol synchronization error will destroy orthogonal between sub-carriers. 码元同步错误破坏载波间的正交性等问题,有必要进行深入的研究。
This paper is based on the DVB-C standard, the feedback loop is adopted to realize symbol synchronization, in which the MM algorithm is choosing into the timing error detector. 根据DVB-C标准,采用反馈环路实现符号同步,其中时钟误差检测器选择MM算法。
