Two nonbinary sequences with six-valued cross correlation

摘要

Let p be an odd prime, p ≡ 3 (mod 4), m be an odd integer and k | m. In this paper, the distribution of 6-valued cross correlation of an m-sequence (st) with length p^2m − 1 and its decimated sequence (sdt) with d = (p^m + 1)²/2(p^k + 1) is determined.
