Performance evaluation of joint processing coordinated multipoint transmission in LTE networks

3GPP Long Term Evolution (LTE) is a standard for wireless communications to achieve high spectral efficiency, high peak data rates, as well as flexibility in frequency and bandwidth. By using frequency reuse of one in LTE networks, high spectral efficiency is achieved. However, the Inter-Cell Interference (ICI) resulted from the frequency reuse of one is a main limitation in these networks. Coordinated Multipoint Transmission (CoMP) has been proposed as an Inter-Cell Interference Coordination (ICIC) technique in Orthogonal Frequency Division Multiple Access (OFDMA) based LTE networks. CoMP forms a cluster of cooperating base stations that jointly transmit data to users within it. This paper focuses on evaluating CoMP method and compare results with the conventional method. A broad comparison among is performed by using a proposed mechanism which depends on Monte Carlo simulations considering performance metrics such as Signal to Interference plus Noise Ratio (SINR), capacity and throughput. Simulation results show that, when CoMP is used, the throughout has generally increased with significant increase at the cell-edge.
