The rank, r, and the dimension of the kernel, k, for binary Hadamard codes of length 2twere studied in [12], constructing such codes for all possible pairs (r,k). Now, we will focus on Hadamard codes of length 2t· s, s1 odd. As long as there exists a Hadamard code of length 4s, constructions of Hadamard codes of length n=2t· s (t≥ 3) with any rank, r ∈ {4s+t–3,..., n/2}, and any possible dimension of the kernel, k∈ {1,...,t–1}, are given.
