摘要
提出了一种只读高密度光盘的DPD信号检测方法,阐述了DPD信号检测中均衡电路和相位检测器的原理和设计方法,并基于CPLD器件实现了光盘高频读出信号的相位差检测。实验结果表明,本文提出的方法可以准确检测光盘的DPD信号。
The paper proposes a novel differential phase detection(DPD) signal detection method for read-only high density optical disk,discusses the desire and design of the equalizer and the phase comparator, and achieves the phase detection of high frequency signal of DVD based on CPLD. The experiment result shows that the detection of DPD signal is correct.
