Abstract: A radio over fiber (RoF) system and a nonlinear compensation method, where the RoF system includes a BBU and an RRU, the RRU includes an electrical component, and the BBU includes a downlink and a feedback link. A predistortion module and an optical component are disposed on the downlink, an input end of the feedback link is connected to an output end of the optical component, and the feedback link is configured to feed back, to the predistortion module, a nonlinear signal output by the optical component. The RoF system further includes a temperature detection module configured to detect a temperature value of the electrical component, and transmit the temperature value to the predistortion module. The predistortion module is configured to perform digital predistortion DPD on a baseband signal based on the temperature value and the nonlinear signal.

Abstract: A small-cell subscriber management method includes receiving, by a terminal, a closed subscriber group (CSG) identity broadcast by a small cell, determining whether the CSG identity is in a CSG identity list stored by the terminal, sending, by the terminal, an access request to the small cell when the CSG identity is in the CSG identity list, requesting, by the terminal after successfully accessing the small cell, a current CSG subscriber list of the small cell from the small cell, managing, by the terminal after receiving the current CSG subscriber list of the small cell, the current CSG subscriber list of the small cell, where a management includes adding a subscriber to, removing a subscriber from, or changing a subscriber in the current CSG subscriber list. According to the foregoing method, a management terminal is used to manage the CSG subscriber list to implement convenient management of a small cell.
