Three New Constructions of 5-valued Spectrum Functions with Totally Disjoint Spectra Duals

2022 · 2022 IEEE International Symposium on Information Theory (ISIT)

A function $f:\mathbb{F}_2^n \to {\mathbb{F}_2}$ is called a 5-valued spectrum function if the Walsh transform Wftakes the values $0, \pm {2^{\frac{{n + {s_1}}}{2}}}, \pm {2^{\frac{{n + {s_2}}}{2}}}$ for some different non-negative integers si,i = 1,2 …
