Abstract
Some upper bounds on the rates of complex orthogonal space-time (COST) block codes were derived. A construction of rate 1/2 COST block codes for phase shift keying (PSK) and QAM symbols was provided using real orthogonal space-time block codes of rate 1. To maintain the fast maximum likelihood (ML) decoding and the full diversity of a space-time block code, the orthonormality that the norms of all column vectors were the same can be relaxed to general orthogonality.
