本文介绍了一种搜索(或构造)用于PCM遥测系统的最佳或准最佳群同步码组的简便方法。它同传统的“穹举法”对比,可以节约计算机工时;并且还可以预先限定其自相关函数的对峰。在雷达、通讯、遥控、光学等技术范畴内,当需要挑最佳或准最佳伪随机序列时,也可应用此法。 This article describes a simple way to search (or construct) the best or quasi-optimal group synchronization code set for a PCM telemetry system. Compared with the traditional “dome lift method”, it can save computer man-hours; and it can also predefine the peak of its autocorrelation function. In the radar, communications, remote control, optical and other technical areas, when the need to pick the best or quasi-best pseudo-random sequence, this method can also be applied.
