摘要
针对在数字解调器中,遇到的对接收信号的采样和接收信号的实际符号率不同步的问题,以DVB-C中对QAM信号接收为例,介绍了一种同步定时方案,并对其关键技术—内插滤波器进行了讨论。
In many cases, sampling of the received data is unsynchronized to the data symbols in digital demodulator. This paper introduces a timing recovery method for QAM in DVB-C demodulator. In this method, interpolation is very important, which is discussed here.
