Notes on the ideal arithmetic correlations of $N$-ary sequences

본문 미리보기

In this paper, we investigate the nonexistence of $N$-ary sequences with ideal arithmetic correlation. We prove that there exist no ternary, quaternary, or $6$-ary sequences with ideal arithmetic autocorrelation when the connection integer is an odd prime power $p^{t}$ and $\textup{ord}_{p^{t}}(N)=\phi(p^{t})/4$, where $\phi$ denotes Euler's totient function. Furthermore, when the connection integer is an odd prime $p$ and $\textup{ord}_{p}(N)=\phi(p)/6$, no such ternary, quaternary, or $6$-ary
