Abstract

A new family of binary sequences Se(ρ) (Ue(ρ)) of period 2n–1 is constructed for odd (even) n=me and an integer ρ with 1 ≤ ρm/2 ⌉. The new family Se(ρ) (or Ue(ρ)) contains Kim and No's construction as a subset if m-sequences are excluded from both constructions. Furthermore, the new sequences are proved to have low correlation property, large linear span and large family size.
