提出一种新的同步方法,当系统空闲时在反向脉冲位置调制(IPPM)保护段设计了一个空闲位,解码时利用空闲位实现时钟校正,有效简化了解码的硬件电路。采用现场可编程门阵列(FPGA)实现IPPM的编解码。
A new synchronization method is proposed, design an idle bit in IPPM's protect time when system is idle, decoding circuit utilize idle bit to achieve the clock correction and it's simplify the hardware circuit for decoding. The Field Programmable Gate A_rray(FPGA) is used to realize IPPM codec.
