Cross-phase estimation for dual polarized microwave transceiver

A method of cross-phase noise compensation on a microwave communication link provided by at least two independent pairs of transmitter/receiver outdoor units (ODUs), the method comprising:

• receiving, by a first one of the at least two independent receiver ODUs, a signal having a first polarization transmitted from a first one of the at least two independent transmitter ODUs of the microwave communication link, the received signal comprising a plurality of transmitted consecutive pilot symbols in temporal proximity to each other;
• and
• compensating, by the first one of the two independent receiver ODUs, the signal having the first polarization by estimating cross-phase noise in the plurality of transmitted pilot symbols wherein cross-phase interference is introduced from a signal having a second polarization orthogonal to the first polarization and transmitted from a second one of the at least two independent transmitter ODUs of the microwave communication link, and wherein estimating the cross-phase noise is performed by the first one of the at least two independent receiver ODUs independently from all of said receiver ODUs other than said first one of the at least two independent receiver ODUs.
