Spatial Modulation of Signals Using Polarization Methods for Wireless Communication Systems in the Optical and Radio Bands

Promising communication systems are developing in the direction of complicating the configuration of networks, expanding the spectrum of signals, integrating terrestrial, satellite, fiber, and open optical technologies. Polarization signal processing methods, conversion of an radio signal into an optical domain, are promising methods for increasing spectral efficiency, as well as reducing the influence of the atmosphere. The paper analyzes ways to increase the information capacity of signals, schematic diagrams of fiber-wireless transmission in the optical and radio ranges, including in the millimeter range, using polarization effects for spatial modulation of information signals. Similar schemes using wireless sections of the network in the optical and high-frequency radio ranges, and fiber lines can be used both in small-scale terrestrial networks and in global coverage.
