Abstract: A system and method for frequency reuse for wireless point-to-point backhaul. Frequency reuse is enabled through the cancellation of interfering signals generated by interference sources. In one embodiment, a conventional dish antenna is complemented with one or more additional auxiliary antennas (e.g., isotropic). The one or more additional auxiliary antennas enable cancellation of interfering signals whose direction of arrival (DOA) is off the dish antenna's bore-sight.

Abstract: 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 horizontally polarized signal, a first RF module configured to convert the horizontally 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 horizontally polarized intermediate frequency (IF) signal. The system also includes a second ODU configured to receive a vertically polarized signal, a second RF module configured to convert the vertically polarized signal into a second I component and a second Q component, and a second modem configured to up-convert the second I and Q components from baseband into a vertically polarized IF signal. The system is configured to share, via an interconnect, the polarized IF signals between the first and second ODUs.

Abstract: 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.
