摘要： 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.

摘要： A method for compensating a movement of an antenna structure having a directive antenna mounted thereto is disclosed. The method comprises obtaining sensor data from a motion sensor, where the sensor data is indicative of the movement of the antenna structure relative to a reference orientation. Moreover, the motion sensor is associated with a set of calibration parameters such that when applied to the obtained sensor data, calibrated sensor data is formed. Further, the method comprises generating a compensation signal at an output for controlling a beam direction of the directive antenna based on the formed calibrated sensor data such that the beam direction is an intended direction of the directive antenna and such that the (unwanted) movement of the antenna structure is compensated. The method further comprises re-calibrating the motion sensor in order to generate a set of calibration coefficients upon either one of an expiry of a predefined time period, a counter reaching a counter threshold, or upon a measured antenna parameter or signal parameter diverging from a parameter range. Once, one of these conditions are fulfilled, the re-calibration is performed by obtaining a received signal strength indication (RSSI) while the beam direction is controlled based on the generated compensation signal, generating the set of calibration coefficients based on the obtained RSSI, and updating the set of calibration parameters for the motion sensor with the determined set of calibration coefficients.

摘要： Systems and methods for linearizing a radio system are disclosed. In some embodiments, a radio system comprises an antenna array, transmit branches comprising respective power amplifiers, a predistortion subsystem comprising predistorters for the transmit branches respectively, a receive antenna element, a transmit observation receiver having an input coupled to the receive antenna element, and an adaptor. The predistorters predistort respective transmit signals to provide predistorted transmit signals to the respective transmit branches for transmission via respective active antenna elements in the antenna array. The transmit observation receiver is operable to receive, via the receive antenna element, a combined receive signal due to coupling between the receive antenna element and the active antenna elements. The adaptor is operable to generate a combined reference signal based on the transmit signals and configure predistortion parameters input to the predistorters based on the combined reference signal and the combined receive signal.

For each such deviation, the second transceiver unit (2) is adapted to transmit information to the first transceiver unit (1) regarding a desired carrier frequency for at least one corresponding transmitter branch (16, 17, 18). The first transceiver unit (1) is adapted to receive said information and the first control unit (3) is adapted to adjust said carrier frequency accordingly.
