【摘要】 帧同步是脉位调制中关键的一部分，其性能的好坏直接影响到整个系统的性能。本文根据脉位调制信号的特点，采用了插入同步头序列的方法，提出了两种性能较好的同步头序列，并且给出了它们的算法。更多还原

【Abstract】 Frame synchronization is a key part in Pulse Position Modulation. The performance of this part affects the whole performance of the PPM system.In terms of the characteristics of PPM sigal,this paper uses the method of interpolating known PPM sequence to obtain frame synchronization. Two kinds of synchronization sequence are studied and algotithms are given.更多还原
