Feasibility analysis of polarimetric-interference alignment beamforming in rich-scattering indoor channels

We analyze the feasibility of polarimetric interference-alignment (PIA) beamforming in rich-scattering indoor channels. PIA harnesses the orthogonal polarization components of electromagnetic waves to provide a signal space for the interference alignment technique proposed by Cadambe and Jafar. We demonstrate that PIA is feasible under common cross-polarization discrimination values and scattering conditions by using a polarimetric multiuser MIMO channel model.
