Abstract
Embodiments of the present disclosure are directed to systems and methods for polarization division multiple access. A polarized antenna system having a plurality of differently-polarized antennas is envisioned for wirelessly communicating with a plurality of user devices in a wireless network environment. Each polarized pair of antenna elements, using a particular frequency, will transmit signals using a polarization-frequency pair and a base station will instruct user devices which polarization-frequency pair they should tune to for processing the appropriate downlink signal. Using OFDMA with a polarized antenna system increases capacity without the need for deploying additional base stations.
