| Abstract: |
| Symmetric 2-adic complexity serves as an important indicator for periodic binary sequences to resist rational approximation attacks. In this paper, the symmetric 2-adic complexity of a class of interleaving cascade binary sequences with 4N(N = 3 (mod 4)) is determined. Our results indicate that the symmetric 2-adic complexity of the discussed sequence is not less than the half of its period under certain conditions. |
