Abstract
Space-time codes from orthogonal designs have two advantages, namely, fast maximum-likelihood (ML) decoding and full diversity. Rate 1 real (PAM) space-time codes (real orthogonal designs) for any transmit antennas have been constructed from the real Hurwitz-Radon families, which also provides the rate 1/2 complex (QAM) space-time codes (complex orthogonal designs) for any number of transmit antennas. Rate 3/4 complex orthogonal designs (space-time codes) for 3 and 4 transmit antennas have existed in the literature but no high rate (> 1/2) complex orthogonal designs for other numbers of transmit antennas exists. In thsis correspondence, we present rate 7/11 and rate 3/5 generalized complex orthogonal designs for 5 and 6 transmit antennas, respectively.
