Improving Performance of Next Generation Cellular Networks (4G) Based on Interference Mitigation Method

Several MIMO technology are introduced to improve the performance factor for next generation systems, closedloop MIMO schemes increase the system capacity as well as cell cover-age in single cell system, Interference occurring in cell network is the dominant issue, unless several multiple-base-station co-operation schemes have been introduced to mitigate or reduce the intercell interference. In this paper we first provide a scenarios and technology categories for multi-Base station MIMO schemes, next we implement closed loop multicell MIMO techniques adopted in IEEE 802.16m, it doesn’t require data forwarding among different base stations. In this paper specifically explains the overall operations which minimize overhead. We also present simulation results, this conform the efficiency of the presented interference mitigation method.
