LTE,CoMP
LTE-Advanced system based on orthogonal frequency
division multiplexing (OFDM) can eliminate intra-cell
interference since data are carried on the orthogonal subcarries;
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.
