Communication System Having Cross Polarization Interference Cancellation (XPIC)

摘要

An all outdoor unit communication system, for performing cross polarization interference cancellation, is provided. The system includes a first outdoor unit (ODU) configured to receive a first directionally polarized signal, a first RF module configured to convert the first directionally polarized signal into a first in-phase (I) component and a first quadrature (Q) component, and a first modem configured to up-convert the first I and Q components from baseband into a first directionally polarized intermediate frequency (IF) signal. The system being configured to communicate, via an interconnect coupled to the first ODU, a second directionally polarized IF signal to the first ODU, and where the first modem is further configured to utilize the second directionally polarized IF signal to cancel out at least a portion of a first cross-polarization leakage at the first ODU.

1. A communication system for performing cross polarization interference cancellation (XPIC), comprising:
a first outdoor unit (ODU) configured to receive a first directionally polarized signal; a first radio frequency (RF) module, implemented within the first ODU, configured to down-convert the first directionally polarized signal into a first in-phase (I) component and a first quadrature (Q) component; a first modem, implemented within the first ODU, configured to up-convert the first I and Q components from baseband into a first directionally polarized intermediate frequency (IF) signal; and an interconnect, coupled to the first ODU, configured to communicate a second directionally polarized IF signal to the first ODU, and wherein the first modem is further configured to utilize the second directionally polarized IF signal to cancel out at least a portion of a first cross-polarization leakage at the first ODU.
