Abstract
An eNodeB in a TDD system (), comprising first and second transmitters (-), a first receiver (-), a control unit (), and means () for diverting part of a transmitted signal from the first and second transmitters (-) to the first receiver (-). The diverting means () are connected to the transmitter part via a switch function () and the transceiver also comprises a delay component (. The control unit () activates the switch () when the output power of the transmitted signals falls below a threshold, and the delay component () delays so that the diverted signals are received by the receiver part (-) at a predefined point in time. The transceiver () comprises a comparison unit () for comparing the diverted signals from the first and second transmitters after reception through the first receiver.
