bounds; linear programming; space time codes; unitary codes; unitary matrices
Summary: The linear programming method is developed in the space of unitary matrices in order to obtain bounds for unitary codes relative to the so-called diversity sum and diversity product. Theoretical and numerical results improving previously known bounds are derived.
