Abstract
The performance of Orthogonalized Spatial Multiplexing (OSM) system is improved by phase rotation precoding. However, the reliability of OSM system can be enhanced further. For this problem, a phase rotation and power allocation precoding is proposed for OSM system, in which the minimum Euclidean distance between the received signal is increased. Both theoretical analysis and simulation results demonstrate that the proposed scheme outperform the phase rotation precoding.
