Polarization Modulation in Wireless Communications
Abstract
The goal of this work is to advance the state-of-the-art in communication techniques involving the direct modulation of signal polarization features. Current techniques described in patents and literature are based on signal polarization states over narrowband channels or subchannels, and they do not assume channel state information at the transmitter. Novel methods leveraging polarization state and other polarimetric features are to be investigated in this research. Polarization-based communications techniques will be developed and analyzed that exploit other signal polarization features, including depolarization and dispersion. Novel overlay techniques will also be considered, including polarization-modulated random noise and overlay techniques imparting redundancy in multi-symbol detection schemes for enhanced reliability. Channel state information at the transmitter will also leveraged to implement joint polarization/space techniques in space-polarization MIMO architectures. The techniques will be evaluated numerically and then analyzed in a laboratory setting over a wide range of emulated channel conditions using Notre Dame’s Space-Polarization MIMO Communications Testbed. Numerous field experiments will also be conducted, facilitated by the acquisition of field research vehicles.
