Abstract

This disclosure provides a microwave radio transmitter for radio transmission to a microwave radio receiver. The microwave radio transmitter comprises an antenna arrangement and a baseband processing module connected to the antenna arrangement. The antenna arrangement comprises an antenna having a polarization. The baseband processing module is configured to receive a polarization misalignment indication from the microwave radio receiver. The polarization misalignment indication is indicative of a misalignment between the polarization of the antenna and a corresponding polarization of a receive antenna comprised in the microwave radio receiver. The baseband processing module is configured to compensate for polarization misalignment between the antenna and the receive antenna by adjusting the radio transmission based on the polarization misalignment indication.
