Unitary Space Time Constellation Analysis: An Upper Bound for the Diversity
<|reference_start|>Unitary Space Time Constellation Analysis: An Upper Bound for the Diversity: The diversity product and the diversity sum are two very important parameters for a good-performing unitary space time constellation. A basic question is what the maximal diversity product (or sum) is. In this paper we are going to derive general upper bounds on the diversity sum and the diversity product for unitary constellations of any dimension $n$ and any size $m$ using packing techniques on the compact Lie group U(n).<|reference_end|>
