Abstract :
LTE-Advanced system based on orthogonal frequency division multiplexing (OFDM) can eliminate intra-cell interference since data are carried on the orthogonal subcarriers; however, it can not mitigate inter-cell interference (ICI) which affects the performance severely. Therefore, coordinated multiple point (CoMP) reception scheme was proposed to reduce ICI and improve the cell capacity for the uplink of LTE-Advanced system. The basic idea of CoMP is to extend the conventional system to a multi-cell MIMO structure by sharing necessary information and received signals across multiple evolved Node Bs (eNB). This paper focus on evaluation of the CoMP scheme in which joint detection with minimum-mean-square-error (MMSE) algorithm is configured at the eNB side to cancel the ICI from other users. To guarantee fairness of the cell-edge users, proportional fair (PF) scheduling method is adopted. Simulation results for uplink show that the CoMP scheme can significantly improve the average cell throughput and reduce ICI for the cell-edge users.
