Abstract
A MIMO transmission scheme is provided which provides some advantages of the Alamouti code but which can be adapted so as to provide enhanced performance for a given amount of antenna correlation. A block of complex scalar input symbols is mapped to a block-code matrix which is transmitted as a spacetime signal matrix from an array of two or more antennas. The block-code matrix is assembled by combining input data with specified dispersion matrices. Each of the dispersion matrices is determined, in part, by an adjustable parameter which relates to a degree of beam-forming behavior by the transmission antenna array.
