Patent number: 9356735Abstract: Although orthonormal space-time coding matrices provide for optimal communication system performance in that associated correlation matrices include no non-zero off-diagonal elements, unity code rate orthonormal coding matrices are difficult to identify for arbitrary communication network equipment. According to embodiments of the present invention, non-orthonormal space-time coding matrices, for which associated correlation matrices include non-zero off-diagonal elements, are used to encode data symbols. The non-orthonormal space-time coding matrices are more easily determined, and undesirable effects of the non-zero off-diagonal components are reduced by selecting a coding matrix from among a number of such matrices. For example, a particular space-time coding matrix may be selected from a number of generated space-time coding matrices based on a number of non-zero off-diagonal elements or a power of a trace of the associated correlation matrices.Type: GrantFiled: September 13, 2012Date of Patent: May 31, 2016Assignee: BlackBerry LimitedInventors: Wen Tong, Ming Jia, Peiying Zhu, Alexandre Mikhailovich Chloma, Mikhail Germanovich Bakouline, Vitali Borisovich Kreindeline
