Trace-Orthonormal Full-Diversity Cyclotomic Linear Dispersion Codes Using Coordinate Interleaving

In this paper, we improve the Trace-orthonormal full-diversity cyclotomic space-time codes using coordinate interleaving. We find that in the original design of full-rate full-diversity cyclotomic linear dispersion codes (FR-FD LDC), the constellation is restricted. Fortunately, a coordinate interleaving method enables not only symbol-level diversity but also coordinate-level diversity for high rate LD code design. Using this method, we can improve the performance of the cyclotomic LD codes over the constellations without the constellation restriction, in block and fast fading channels.
