In classical electromagnetism, polarization density (or electric polarization, or simply polarization) is the vector field that expresses the density of permanent or induced electric dipole moments in a dielectric material. When a dielectric is placed in an external electric field, its molecules gain electric dipole moment and the dielectric is said to be polarized. The electric dipole moment induced per unit volume of the dielectric material is called the electric polarization of the dielectric.
Adaptive cross polarization interference mitigation
Various arrangements for cross-polarization interference mitigation are detailed herein. A baseline cross-polarization interference density limits of a user terminal (UT) and a baseline throughput of the UT can be determined. An adjustment value can then be determined for an intended polarization (co-pol) isotropic radiated power (EIRP) density, such that the cross-polarization (x-pol) interference density limits are not exceeded. After determining the baseline throughput, an effective co-pol EIRP density of the UT can be set based on the adjustment value. After adjusting the effective co-pol EIRP density of the UT, an adjusted spectral efficiency of the UT can be determined resulting from the adjusting the EIRP density. Finally, an allocated bandwidth to the UT can be adjusted such that a resulting adjusted throughput of the UT at the adjusted spectral efficiency matches the baseline throughput.
