Performance Analysis of Coordinated Multi-point with Scheduling and Precoding Schemes in the LTE-A System

To meet the requirements of users for quality of data services, techniques which can support a high data rate to users located within the cell edge as well as the cell center would be indispensible. Accordingly, the need for efficient methods to control the interference between transfer points is increasing. In current standards and academic issues the way of how to control the interference from point-to-point transmission naming coordinated multi-point (CoMP) was selected as the work items for 3rd Generation Partnership Project (3GPP) long term evolution-advanced (LTE-A) Release 11. This paper proposes a combined system of CoMP with Scheduling and Precoding, which solves the problem of conventional cellular system and improves the spectral efficiency of overall system. We design and analyze the performance of the Coordinated Beamforming technique, which is one major category of CoMP. The parameters are included in order to fulfill the requirements of the 3GPP LTE-A Standard. Finally, we make a performance analysis of the proposed system through the system level simulation in Homogeneous Network and Heterogeneous Network. We confirm the performance through a graph of the cumulative distribution function about signal to interference plus noise ratio.
