Abstract
It has been shown that a complex orthogonal design that provides full diversity and full transmission rate is not possible for more than two transmit antennas. This paper presents a new class of quasi-orthogonal space-time block codes using a group-theoretic method. The new designs can achieve full diversity for quadrature phase-shift-keying modulation, like the system using the rotated constellations. Based upon the analysis of the new codes, a relaxed designing viewpoint for full diversity is proposed for arbitrary signal constellations.
