Abstract
A remote radio unit is for a base transceiver station. The remote radio unit includes: a noise generator configured to provide a RF noise signal having predefined statistical properties; a communication interface configured to transmit the RF noise signal as a stimulus signal over a radio-over-fiber uplink channel between the remote radio unit and a central unit of the base transceiver station for determining a pre-distortion of a target signal to be transmitted by the remote radio unit. The communication interface is further configured to receive the pre-distorted target signal over a ROF downlink channel between the remote radio unit and the central unit of the base transceiver station. The remote radio unit also has an antenna for transmitting the pre-distorted target signal received by the communication interface.
