| Abstract: | In this paper,a new sampling sequence is designed,it's characteristic polynomial,and period are presented.As sampling sequence is controlled by de Bruijn sequence,its bounds on the linear complexity and on the weight complexity WCn(u).When n is one are also given.In a full period of the sampling sequence,the relative difference which refers to the number of occurrence of ones and zeros is very small,so the sampling sequence has good pseudo-random properties. |

| Keywords: | sampling sequence characteristic polynomial period minimal Polynomial linear complexity |
