| Title: Adaptive Transmission of Wireless Optical MIMO in Atmospheric Composite Channel | |
| Abstract: Adaptive transmission technology provides a feasible solution to suppress the impact of atmospheric turbulence on laser signal transmission and improve the performance of communication links under various channel conditions. It is challenging to apply the link adaptation technology in SISO FSO to MIMO links to cope with the spatiotemporal changes in refractive index caused by turbulence. Due to the introduction of new adaptive dimensions in MIMO-FSO links, different spatial modes can provide different multiplexing and diversity gains, making the design of link adaptive transmission schemes more challenging. This report explores adaptive transmission technologies for MIMO wireless optical communication links, including research results based on MIMO adaptive subcarrier modulation, MIMO adaptive spatial mode switching, and estimation of turbulent channel fading parameters. | |
