脉冲位置调制的字同步技术

Word Synchronization Of Pulse Position Modulation

对脉冲位置调制的关键技术，即时隙同步、字同步和帧同步中的字同步技术提出了一种新的解决方案。该方案利用信号自身的特性，采用数字逻辑设计，有效避免了性能不高的锁相环的使用。

A new scheme for word synchronization in pulse position modulation is proposed. The most important issue in pulse position modulation is the receiver synchronization subsystem which maintains necessary decoder timing, thus accomplishes the PPM data deduction which contains three levels of Synchronization (slot, word and frame). In the new scheme proposed, the phase lock loop is avoided and the digital logical circuit is used.
