Closed-loop quasi-orthogonal STBCs and their performance in multipath fading environments and when combined with turbo codes.
Quasi-orthogonal space-time block codes (QO-STBCs) achieve full code rate at the expense of loss in diversity gain. We propose two feedback methods for QO-STBCs to achieve full diversity and full code rate. In the first method, signals radiated from various antennas are rotated by phasors according...
