摘要 描述了以8-ASK作为调制方式的ATSC全数字接收机解调中定时同步问题的解决方法:通过采用基于Farrow结构的sinc()响应FIR,Gardner算法的定时误差检测方法,实现了符号同步。Matlab仿真表明,Gardner算法适用于ATSC接收机的符号同步设计。 The interpolation filter with Sinc impulse response based on Farrow structure is used to resolve the problem of timing synchronization in ATSC receiver. And Gardner Timing error correction is used to get timing error information.
