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.
