| 摘要 | The examples of the present invention disclose an anti-interference method and device in a common-frequency networking mobile communication system. The method includes: creating a candidate cell list according to probability that each adjacent cell of a current cell interferes with the current cell; selecting a selected cell list from the candidate cell list according to the probability; performing 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, and selecting a detected cell list from the selected cell list according to the signal power; and performing 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. | ||
