Method and apparatus for eliminating interference between adjacent cells

The invention discloses a method for eliminating the interference of nearby regions, wherein user device UE obtains the midamble setting information of each nearby region, while the information comprises midamble shift distributing method and midamble setting parameter K, the UE according to the midabmle setting parameter K for each nearby region which midabmle shift distributing method is default obtains the relation between the midabmle shift and channel code of nearby regions, and the UE according to the relation checks relative nearby regions to obtain signal evaluation, via which to eliminate the interference of nearby regions. The invention also discloses a communicator and a TDD-CDMA communication system.
