METHOD AND DEVICE FOR ANTI-INTERFERENCE IN SINGLE FREQUENCY NETWORK OF MOBILE COMMUNICATION SYSTEM

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. The device includes a candidate cell list maintaining module, a selected cell list maintaining module, a detected cell list maintaining module and an anti-interference module. By the present invention, the ability that each cell in the mobile communication system decreases the interference of common-frequency adjacent cells can be enhanced, and the complexity of the device for performing anti-interference processing at the network side can be decreased.
