摘要：Although orthonormal space-time coding matrices provide for optimalcommunication system performance in that associated correlation matrices include nonon-zero off-diagonal elements, unity code rate orthonormal coding matrices aredifficult to identify for arbitrary communication network equipment. According toembodiments of the present invention, non-orthonormal space-time coding matrices, forwhich associated correlation matrices include non-zero off-diagonal elements, are usedto encode data symbols. The non-orthonormal space-time coding matrices are moreeasily determined, and undesirable effects of the non-zero off-diagonal components arereduced by selecting a coding matrix from among a number of such matrices. Forexample, a particular space-time coding matrix may be selected from a number ofgenerated space-time coding matrices based on a number of non-zero off-diagonalelements or a power of a trace of the associated correlation matrices.
