| 摘要 |
The invention relates to a mobile radio base station comprising a transmitter (TRX) for each transmission frequency, and a plurality of receivers (RX 1, RX 2, RX 3, RX 0). The outputs of individual antennae (AN 1, AN 2, AN 3) or of a matrix network (BUM) and of at least one omnidirectional antenna (AN 0) are connected to transmitting/receiving switches (SE 1, SE 2, SE 3, SE 0). The receiving branches of the switches are routed to the individual receivers (RX 1, RX 2, RX 3, RX 0). The transmitting branches of the switches are selectively connected to the output of a transmitter (TRX) via a controlled switching device (SWI). A common detector (DET) is provided for processing the output signals of the receiver. Said detector is disposed to deliver a control signal (stw) to the switching device via an antenna control (AST) such that the transmitter is connected to an antenna determined in the detector (DET). |
