“…Multipath environments are known to have a depolarization effect on point-to-point wireless communications [5,6]. Modern wireless systems exploit such depolarization through the use of multiple-polarization antenna arrays to increase channel capacity, but for energy-constrained wireless sensor applications, link reliability is of much greater concern than capacity.…”

Abstract-Wireless communications within enclosed environments such as aircraft and vehicles have been shown to experience fading with statistics that are worse than Rayleigh. Motivated by low-cost, low-complexity systems (e.g., wireless sensors) that may be deployed in such environments, this work explores the benefits of polarization diversity using very large data sets collected over a small area and over the 5-6 GHz band. The results also demonstrate that antennas capable of capturing depolarized signal components can significantly mitigate the harshest of fading environments.

Abstract. Dual-polarized antenna (DPA) systems can provide two independent data transmissions in line-of-sight wireless channel environments. The capacity of each data stream can be affected by a rotation angle between transmitter and receiver DPAs and channel gains of vertical and horizontal receiver antennas. In this paper, we propose a user selection scheme for the DPA system. In the proposed scheme, the best DPA user is selected based on both the rotation angle and the channel gains. By using this scheme, the capacity of the DPA system increases two times when the selection order is three. The selected best user can even achieve 3 times of capacity when the selection order is six.
