摘要
近年来，无线通信对高数据速率的需求日益增长。然而，在蜂窝边缘等情况下，用户设备同时接收来自某些传输节点的传输信号，吞吐量性能变差。为了解决这一问题，本文提出了采用准正交空时分组码(Quasi Orthogonal Space - Time Block Code, QO-STBC)作为蜂窝边缘用户吞吐量性能求解方法的CoMP传输。仿真结果表明，该系统在蜂窝边缘用户的吞吐量性能上优于时分算法。
Enhancement of cell-edge throughput performance with CoMP transmission using QO-STBC scheme
Recently, there has been growing demand for high data rate in wireless communication. However, under the situation such as cell-edge that user equipment simultaneously receives transmitted signals from some transmission nodes, throughput performance becomes worse. To solve this problem, in this paper, we propose the CoMP transmission applying Quasi Orthogonal Space Time Block Code (QO-STBC) as the method of solution for cell-edge user throughput performance. From simulation results, we showed that proposed system is superior to time-division method in throughput performance for cell-edge user.
