Applications of n-to-1 Mappings in Difference Families and Optimal Constant Weight Codes

This paper investigates novel applications of <inline-formula> <tex-math notation="LaTeX">$n$ </tex-math></inline-formula>-to-1 mappings over finite fields to the construction of difference families, constant weight codes, and constant composition codes, which play crucial roles in optical code-division multiple access...
