高速可编程PCM遥测帧同步器

A HIGH-RATE PROGRAMMABLE PCM TELEMETRY FRAME SYNCHRONIZER

依据国际最新遥测地面站的发展方向，给出了一种新型高码率可编程ＰＣＭ（脉冲编码调制）遥测帧同步器的方案设计，既采用了高速可编程全数字化相关检测技术及新颖的滑动窗口技术，又采用了状态机变量设计和微程序设计．并基于ＰＬＤ（可编程逻辑阵列）技术，完成了整个高速可编程ＰＣＭ遥测帧同步器的软、硬件设计．实验表明，该方案切实可行．

According to the state-of-the-art technology of the telemetry ground in the world. ascheme and design of the new high--r.ate programmable frame synchronizer in PCM telemetrysystem is introduced in this paper. It not only adopts a high-rate full-digitalized correlationdetector with a new slipping threhold window. but also uses the design of the development ofthe status machine and the microprogram. This high(rate programmable PCM telemetry synchronizer based upon the PLD technology has been fulfilled. The result of the experimentshows that the scheme and development are successful.
