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： The present invention relates to a method and apparatus in a digital communication system that employs phase-aided adaptive modulation to overcome phase noise impairments. The transceiver is configured to transmit a message comprising channel symbols from a primary and a secondary set of channel symbols, wherein the primary set of channel symbols comprises channel symbols having different phase with respect to one another and the secondary set of channel symbols comprises only channel symbols with a fixed known phase.

摘要： There is provided mechanisms performed by a control device for suppressing interference in a received reception signal in a radio transceiver device. The radio transceiver device is configured to receive the reception signal as a radio reception signal and to generate a radio transmission signal. The radio transmission signal and the radio reception signal occupy at least partly non-overlapping frequency bands. A method comprises obtaining a transmission reference signal based on the radio transmission signal. The method comprises estimating an interference distortion component signal based on the transmission reference signal and on a model of nonlinearity in a radio circuit of the radio transceiver device. The method comprises suppressing interference in the reception signal by combining the reception signal with the distortion component signal.

摘要： A receiver for signals, comprising an amplifier arranged to receive and amplify the signals received by the receiver. The receiver also comprises a linearizer arranged to linearize the amplitude value of the output signals from the amplifier. In the receiver, the linearizer is arranged to perform said linearizing by means of determining actual and desired values of a statistical function for the amplitude values of the output signals from the amplifier and to replace the amplitude values of the output signals from the amplifier with amplitude values which have the same desired values of the statistical function. In embodiments of the receiver, the statistical function is the cumulative distribution function.

摘要： The present disclosure relates to methods and arrangements for controlling point-to-point microwave transmission on a microwave link between a first and a second microwave network node, wherein the microwave link is configured for payload data transmission at a payload data rate. The method comprises obtaining information indicative of a current data rate capability of the microwave link and comparing the current data rate capability to the configured payload data rate. When the current data rate capability is below the configured payload data rate, transmission on the microwave link is adapted to comprise transmission of dummy data on the microwave link between the first and second microwave network node.
