Power Allocation-Aided Spatial Modulation for Limited-Feedback MIMO Systems

Adaptive power allocation (PA) algorithms based on optimization of the minimum distance dmin between signal points at the receiver side are investigated in spatial modulation (SM) systems. First, a closed-form solution of the optimal maximum-dmin-aided PA algorithm is derived in the case of two transmit antennas (TAs). Moreover, for a higher number of TAs, we propose a numerical approach, which appropriately splits the power between the specific TA pair associated with dmin to increase this distance. Furthermore, our PA-aided SM systems may be readily combined with adaptive modulation (AM) to further improve the system's performance. Our numerical results show that the proposed algorithms provide beneficial system performance improvements compared with both the equal-gain PA-based SM and the identical-throughput PA-aided spatial multiplexing systems.
