Generalized Rao Bound for OOAs
Martin and Stinson [1, Theorem 3.5] show that for an even k ≥ 2 an ordered orthogonal array OOA(M, s, Sb, T , k) can only exist if
where Vb(s,T )(r) denotes the volume of a ball with radius r in the NRT-space Sb(s,T ).
The dual to the Rao bound for OOAs is the Hamming bound or sphere-packing bound in NRT space, which was established in [2, Theorem 3]. Using duality [3], it yields the Rao bound for linear OOAs.
It is shown in [4, Section 5] that the generalized Rao bound follows also from the linear programming bound for OOAs.
