Abstract :
By reducing the problem of finding aperiodic sequence bounds to that of minimizing a quadratic form, several lower bounds on the aperiodic correlations of binary sequences with low or zero correlation zone are established. It is shown that the new bounds are tighter than the existing bounds.
