One of the most critical points in optical PPM radio communication lies on the recovery of slot clock and framesynchronizationsignal.
P PM无线光通信的关键问题之一在于时隙时钟与帧同步信号的恢复。

The first kind of the framesynchronization algorithm employs the correlation of the long PN sequence and the redundancy of the guard interval to produce the synchronization signal.
第一种帧同步算法直接利用了一个长PN序列产生相关并融合保护间隔的冗余特性获得同步信号。

In the extract process, through the decoding of the synchronization code to locate the position of the watermark signal embedded in the frame as well as data starting position.
