Binary signature set with optimal odd periodic total squared correlation

In this paper, we give a lower bound on odd periodic total squared correlation (OPTSC for short) of binary signature sets, which indicates that odd periodic complementary sets and PTSC-optimal signature sets of odd period can be used to design optimal OPTSC signature sets which achieve the new lower bound. Besides, we give three kinds of PTSC-optimal signature sets from ideal sequences and large Kasami subsets.
