A device () comprising an antenna array () having a plurality of transmit and receive antennas () for wireless radio communication and a display () for displaying a stereoscopic image (), wherein the stereoscopic image () is visible to an observer (A,B) at a position (A,B), wherein the antenna array () and the display () are arranged so that from the position (A,B) the observer's view of at least a part of the antenna array () is obstructed by the display (). A method for operating the device.

Device for communication, method of operating such device

A leaky repeater access node (LRAN) includes a first directional antenna and a second directional antenna to transmit and receive signals in at least one first frequency band, and a third antenna to transmit and receive signals in a second frequency band. The LRAN also includes first analog components to split a first signal received by the first directional antenna into a first portion and a second portion. The first analog components amplify the first portion and provide the amplified first portion to the second directional antenna. The first analog components also convert the second portion to the second frequency band and provide the converted second portion to the third antenna.

In a method for transmitting data through a Massive MIMO backhaul system, a central node of the MIMO backhaul system transmits, to a small cell repeater terminal on the downlink, a downlink pilot signal carrying a set of pilot sequences that are mutually orthogonal in the frequency domain. Each pilot sequence in the set of pilot sequences corresponds to an antenna of an antenna array at the central node. The central node receives an uplink pilot signal carrying the set of pilot sequences transmitted by the small cell repeater terminal on the uplink, where the received uplink pilot signal is a frequency converted retransmission of the downlink pilot signal. The central node estimates at least one of an uplink channel and a downlink channel between the central node and the small cell repeater terminal based on the set of pilot sequences and the received uplink pilot signal.

The present invention relates to a method for configuring a base station () of a mobile communication network over a software defined radio module (), that base station () serving at least one mobile terminal () over an air interface () served by that software defined radio module. When selecting the communication standard for the configuration of the base station () the characteristics of the air interface () are taken into account. The invention also relates to a base station () of a mobile communication network, that base station () serving at least one mobile terminal () over an air interface (), that base station () comprising a configurable software defined radio module (). The configurable software defined radio module () is adapted to take into account the characteristics of the air interface () when selecting the communication standard for the configuration of the base station ().

Method of correcting a gain and phase imbalance of an analogue modulator () for multiple channels (CHi) of a multi-carrier transmission signal, the method comprising the steps of determining a gain imbalance correction factor (GCFi) and phase imbalance correction factor (PCFi) for each channel individually and applying said correction factors (GCFi, PCFi) to the corresponding channel (CHi) individually, before the multi-carrier synthesis of the channels is done, whereas step a) for each one of the multiple channels (CHi) is performed in a time-multiplexed manner with step a) for the other ones of the multiple channels (CHi).
