摘要
对帧同步码相关检测是关系到高速可编程PCM遥测帧同步器可靠工作的关键技术。提出了一种新的全数字化相关检测器——基于PROM多输入并行加法网络实现的数字相关器,并详细给出了这种数字相关器的硬件设计方法和软件生成算法。系统实验表明,这种PROM化并行加法网络应用于高速可编程PCM遥测帧同步器是行之有效的。
The reliability of the PCM telemetry synchronizer depends directly on the correct correlation detection of synchronization codes.A new type of whole-digitized correlation detector based on PROM's multiple-input parallel addition network is introduced.The implementation of its hardware design and the algorithm of its data-table generation are discussed in detail.The experimental results indicate that the application of PROM's multiple-input parallel addition network to the high-bit-rate programmable PCM telemetry frame synchronizer is successful.
