Hadamard matrices and Z4-linear codes
A Z4-linear code of length n is a Z4 sub-module of Z4^n. In the Pless-Leon-Fields article "All Z4 codes of Type II and length 16 are known" a method for construction of self-dual Z4-linear codes is presented. The starting point of this construction is a doubly-even self orthogonal binary code. It is known that binary linear codes obtained from Hadamard 3 designs satisfy these conditions. In this talk I will present a method for obtaining binary codes from Hadamard 3-designs of length 4n starting from skew-symmetric Hadamard matrices of order n. Also I will present some Z4-linear codes that we obtained so far and some partial results. This is joint work with Dean Crnković and Sanja Rukavina.
