我们发现新的家庭的非二元序列的周期p/supn/-1的符号从有限域F/sub p/为任何素数p/spl ges/3。该序列具有两级的理想自相关性,并且是以前发现的具有理想自相关性的三元序列的推广。具有参数((p/sup n/-1)/(p-1),(p/sup n-1/-1)/(p-1),(p/sup n-2/-1)/(p-1))的差集也可以从这些序列以自然的方式导出。
We find new families of nonbinary sequences of period p/sup n/-1 with symbols from a finite field F/sub p/ for any prime p/spl ges/3. The sequences have two-level ideal autocorrelation and are generalizations of previously found ternary sequences with ideal autocorrelation. Difference sets with parameters ((p/sup n/-1)/(p-1), (p/sup n-1/-1)/(p-1), (p/sup n-2/-1)/(p-1)) can also be derived from these sequences in a natural way.
