本文提出了一种产生除零移峰值外周期相关为零的任意长相移脉冲码的方法。这些码的长度为p^2，其中p是任何素数，生成它们需要对应于p次单位根的p个不同相移。由于需要p个不同的相移，这些代码不像二进制代码那样容易生成和处理，但这似乎并不严重限制它们的用途。这些码的应用可以作为脉冲间相位调制，用于脉冲多普勒雷达中的距离分辨率或用于同步脉冲码通信系统的方法。
A method of generating phase shift pulse codes of arbitrarily long length with zero periodic correlation except for the peak for zero shift is presented. The codes are of length p^2 where p is any prime number, and p different phase shifts corresponding to the p th roots of unity are necessary to generate them. Since p different phase shifts are required, these codes are not as easy to generate and process as the binary codes, but this does not seem to be a serious limitation to their usefulness. Application of these codes can be made as interpulse phase modulation for range resolution in pulse Doppler radars or for a method of synchronizing a pulse code communication system.
