经过限带滤波后的QDPS K信号的码元波形可分为稳定区与过渡区，根据这一特点可以利用DFT方法来实现信号的解调和位同步。
After a bandpass filter, QDPSK signal's symbol can be divided into steady section and transition section, so the demodulation and synchronization for the signal can be realized with DFT.
该系统采用了片同步技术实现了采样后高速数字信号的可靠锁存，采用高精度的时钟管理芯片和设计合理的时钟路径对时钟抖动做了严格控制。
The Chip-Sync technology has been used to ensure the latch of high-speed signal, and we use high accuracy clock management chips and design reasonable clock way to strict control the clock jitter.
在接收方，接收器把LVDS差分信号合成后再还原成原来的视频数据信号、同步信号以及状态指示信号等。
In receiver department, the receiver combined LVDS difference signals and then restored to original video data signal, synchronization signal, state indication signal and so on.
