Abstract (en)
[origin: WO2016057304A1] A distributed antenna system includes a multiple-input and multiple-output (MIMO) base station 252 configured to output at least a first signal Ch1 and a second signal Ch2. At least one master unit 260 communicates with the MIMO base station 252. At least one remote unit 262, 264 communicates with the master unit 260. At least one antenna 270 is coupled with the remote unit 262, 264 for receiving signals from the remote unit. A hybrid coupler 274 is coupled between the remote unit 262, 264 and antenna 270 and is configured to receive the first signal Ch1 and the second signal Ch2 from the remote unit 262, 264 on respective first and second ports and to provide an output signal on at least one output port. The output signal includes at least a portion of the first signal Ch1 and at least a portion of the second signal Ch2. The antenna is coupled with the output port.
