首先给出了现有FSK定时同步算法的优缺点,接着研究了一种基于DTTL环的FSK定时同步方法。此定时方法结构简单,且易于数字实现。最后,并利用MATLAB软件做了仿真,证明了此方法的可行性及有效性。
Firstly, the advantages and disadvantages of the existing FSK timing synchronization algorithm are given. Then a FSK timing synchronization method based on DTTL ring is studied. This timing method is simple in structure and easy to implement digitally. Finally, the simulation with MATLAB software proves the feasibility and effectiveness of this method.
