A joint precoding algorithmZero Force-Tomlinson-Harashima Precoding (ZF-THP) algorithm is proposed based on overlapped clustering model. Then, two problems in existing clustering scheme are investigated and corresponding resolutions are designed by employing the ZF-THP algorithm: one is an inter-cluster interference mitigated scheme; the other is an overlapping clustering scheme under the condition of asymmetry of Degree Wiliness to Cooperate (DWC). Simulation results show the scheme proposed performs better than other conventional clustering algorithm in the system spectrum efficiency, and enhances the capacity of partial users fairness.
