Patent ID: 8812038

Claim:
An anti-interference method in a common-frequency networking mobile communication system, comprising: creating, by a device at a network side, a candidate cell list according to probability that each adjacent cell of a current cell interferes with the current cell, and storing the candidate cell list and probability that each adjacent cell in the candidate cell list interferes with the current cell; selecting, by the device at the network side, a selected cell list from the candidate cell list according to the probability that each adjacent cell in the candidate cell list interferes with the current cell, and storing the selected cell list; performing, by the device at the network side, channel estimation for adjacent cells in the selected cell list, obtaining current signal power of each adjacent cell in the selected cell list according to a channel estimation result, selecting a detected cell list from the selected cell list according to the signal power, and storing the detected cell list; and performing, by the device at the network side, joint detection for adjacent cells in the detected cell list to eliminate interference of the adjacent cells in the detected cell list on the current cell.
