Abstract: In an embodiment, a remote antenna unit includes a transmitter, a receiver, an antenna, a first interference circuit, and a second interference circuit. The transmitter is configured to generate a transmit signal, and the receiver configured to process a receive signal. The antenna is coupled to the transmitter and the receiver and is configured to radiate a downlink signal in response to the transmit signal and generate the receive signal in response to an uplink signal. The first interference circuit is coupled to the transmitter and the receiver and is configured to receive an analog signal from the transmitter. The second interference circuit coupled to the transmitter and the receiver. The first interference circuit and the second interference circuit are configured to reduce, in the receive signal, interference caused by the transmit signal and/or at least one downlink signal radiated by an antenna.

Abstract: A distributed antenna system includes a master unit configured to receive at least one set of multiple input multiple output (MIMO) channel signals from at least one signal source. The master unit is configured to frequency convert at least one of the MIMO channel signals to a different frequency from an original frequency, and combine the MIMO channel signals for transmission. An optical link couples the master unit with a unit remote from the master unit for transceiving the MIMO channel signals. Conversion circuitry is configured to frequency convert at least one of the first and second MIMO channel signals from the different frequency back to an original frequency for transmission over an antenna.
