<p>An eNodeB in a TDD system (100), comprising first and second transmitters (408-411 ), a first receiver (302; 402-405), a control unit (306, 416), and means (305, 415) for diverting part of a transmitted signal from the first and second transmitters (408-411 ) to the first receiver (302; 402-405). The diverting means (305, 415) are connected to the transmitter part via a switch function (308, 418) and the transceiver also comprises a delay component (304, 404. The control unit (306, 416) activates the switch (308, 418) when the output power of the transmitted signals falls below a threshold, and the delay component (304, 404) delays so that the diverted signals are received by the receiver part (303; 402-405) at a predefined point in time. The transceiver (300) comprises a comparison unit (307, 417) for comparing the diverted signals from the first and second transmitters after reception through the first receiver.</p> |
