摘要：
We study fast decodability for general rate space-time block codes. We derive bounds on the number of generators that can be in mutually orthogonal groups and use these to show that that the ML decoding complexity of a full-rate n x n space-time block code is unfortunately quite high: at least of the order of vertical bar S vertical bar(n2+1), where S is the effective real constellation. We also show that g-group decodability is not possible for full-rate codes.
