The channel sharing in wireless networks leads to user mutual interference, which also exists in the centralized, cooperative, cloud, and clean-radio access network (C-RAN) which is considered as the access architecture of the 5G mobile communication system. In this paper, the problem of uplink interference suppression in the architecture of C-RAN wireless network was investigated. Taking advantage of the centralized processing in the C-RAN architecture, the correlations of the signals from each RRU are analyzed, based on which we proved that under certain condition, interference can be eliminated by utilizing the correlations among signals. According to the theory before, interference matrix between network users was established based on signals from each user to its nearby RRU. Then, the interference cancellation matrix can be gotten. The uplink signals in the network were processed by making use of the interference cancellation matrix, which can turn the interference part caused by the transmit signal of mobile terminal into useful signal.
