摘要： There is provided a radio transceiver device. The radio transceiver device comprises an antenna. The radio transceiver device further comprises a signal processing module. The radio transceiver device further comprises a receiver chain configured to receive a first signal. The receiver chain extends from the antenna to the signal processing module and at least comprises an analog-to-digital converter (ADC), and is thereby configured to receive a first signal from the antenna and provide the first signal to the signal processing module after application of analog-to-digital conversion in the ADC to the first signal. The radio transceiver device further comprises a transmitter chain. The transmitter chain extends from the signal processing module to the antenna and at least comprises a digital-to-analog converter (DAC), and is thereby configured to receive a second signal from the signal processing module and provide the second signal to the antenna after application of digital-to-analog conversion in the DAC. The DAC is configured to generate a dither signal and is connected to the receiver chain for application of the dither signal to the first signal before application of analog-to-digital conversion in the ADC to the first signal.

摘要： The present invention relates to a solution for efficient handling of radio resources in communication devices in a wireless communication network. In the solution a subset of available antennas to be used is chosen using a method for determining a singular valued metric from a sub matrix related to a full channel matrix. Sub-channel matrices are chosen by deducing the metric and comparing to other sub-matrices. Preferably the best sub-channel matrix is used to determine a suitable full channel matrix to use in communication and this full channel matrix is communicated to each involved communication device.

摘要： The disclosure relates to a method and system for alignment of an antenna (4a, 4b) in a microwave radio link system in Non-Line-Of Sight (NLOS) conditions. The method comprises the steps of: • Having a pointer (1) indicating a first position on a surface (2) to define a first candidate reflection/diffraction point (3:1) on the surface (2) • Aligning a first antenna (4a) at a first node (A) and a second antenna (4b) at a second node (B) towards the first candidate reflection/diffraction point (3:1) • Record a relevant property concerning the channel quality between the first node (A) and the second node (B) via the first candidate reflection/diffraction point (3:1). The system comprises the features of: • a first antenna (4a) at a first node (A) • a second antenna (4b) at a second node (B) • a pointer (1) for indicating a position on a surface (2) to define a candidate reflection/diffraction point (3:n) on the surface • a record unit for reading a relevant property concerning the channel quality between the first node (A) and second node (B) via the candidate reflection/diffraction point (3:n). By repeatedly changing candidate reflection/diffraction points and comparing the channel quality for a multitude of candidate reflection/deflection points (3:n, n=1 to N) may a preferred reflection/diffraction point (3:p) be selected towards which the first antenna (4a) and the second antenna (4b) are aligned.
