On the Optimality of the Selection Transmit Diversity for MIMO-FSO Links with Feedback
We propose an optimal power allocation strategy for Multiple-Input-Multiple-Output (MIMO) Free-Space Optical (FSO) links with Intensity Modulation (IM) and Direct Detection (DD). The optimization is performed for shot noise limited systems in the presence of complete feedback. The derived analytical...

| Summary: | We propose an optimal power allocation strategy for Multiple-Input-Multiple-Output (MIMO) Free-Space Optical (FSO) links with Intensity Modulation (IM) and Direct Detection (DD). The optimization is performed for shot noise limited systems in the presence of complete feedback. The derived analytical solution turns out to be the same as the selection transmit diversity scheme proposed for MISO-FSO systems corrupted by Gaussian noise. We also propose and analyze a novel transmission strategy for the limited-feedback case. |
