Through compose sequences, specially orthogonal sequences, we can construct other new sequences with more length and more security. In our short communication we show how we can use this idea for getting, in some times, new orthogonal sequences from other know orthogonal sequences.

Keywords: Orthogonal Sequences; Walsh Sequences; M-Sequences
