| Abstract: |
| For the inter-cell co-channel interference problems in cellular networks,the paper studies the decoupled filter aiming at the cancellation of co-channel interference.The filter is imposed on whitening the interference and the noise,with the remained desire signal giving off the original symbols based on a non-linear equalization.Based on the discussion on the improvement of the filter,mainly according to the modulation of desire signal and the coverage of interference signal,different receivers are designed.Performance simulation enables a conclusion that the designed filter can be quite good trade-off in complexity and best performance. |
