Investigation of Polarization Deficiencies in SIMO Systems in Random-LOS Propagation Channels
Paper i proceeding, 2015

We study the probability of detecting the bitstream of a 2 x 1 SIMO polarization-diversity system with co-located orthogonally polarized antenna ports on the receiving side of a free-space propagation environment with arbitrary angle-of-arrival, i.e., in so-called Random-Line-Of-Sight (Random-LOS) propagation environments. We show how the diversity gain degrades in directions where the two orthogonal ports have non-orthogonal far-field functions or an amplitude imbalance. We also show that the system performance is better when one side of the link is circularly polarized and the other side is linearly polarized.
