  • Microwave radio transmitter and receiver for polarization misalignment compensation
    Patent number: 10171143
    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.

  • Microwave radio transmitters and related systems and methods
    Patent number: 9654153
    Abstract: This disclosure provides a microwave radio transmitter apparatus comprising an antenna arrangement and a precoder module connected to the antenna arrangement. The precoder module comprises an estimation module. The precoder module is configured to receive a number N of signals s1, . . . , sN and to generate N phase-adjusted transmit signals TX1, . . . , TXN. The antenna arrangement comprises N antenna elements ai, i=1, 2, . . . , N. Each antenna element ai is configured to obtain a respective phase-adjusted transmit signal TXi from the pre-coder and to transmit the respective phase-adjusted transmit signal TXi. The precoder module is configured to obtain an observation receive signal RX, the observation receive signal comprising signals transmitted from the N antenna elements. The estimation module is configured to estimate for each antenna element ai a phase difference between the corresponding transmit signal TXi and the observation receive signal RX.
