OMIMO – Optical multiple input multiple output transmission

Common free space optical communication systems use intensity modulation, which has the drawback of a low spectral efficiency. However, OMIMO is an improved concept for free space optical (FSO) communication. To enhance efficiency a coherent transmission is used with incoherent light sources.
At the transmitter a baseband signal is phase-shifted for precoding, spatial multiplexing or beam forming. After upconversion of the baseband signal to a bandpass signal a DC-offset is added. This signal drives a light source, e. g. an LED or a laser diode by direct modulation. The receiver works with a reverse scheme. For transmitting and receiving a plurality of light source and photo detector can be used in parallel, respectively, to establish an optical MIMO concept.
