| 摘 要： | 协作多点传输与接收(Coordinated Multiple Point transmission and reception,CoMP)技术作为提高小区吞吐量尤其是小区边缘用户吞吐量的关键技术,目前已经成为LTE-Advanced的研究热点之一。就其中基于SU-MIMO的下行联合传输(CoMP-SU-MIMO)技术进行了研究,分析了系统模型,提出了用户信干噪比(SINR)的计算方法。最后对系统进行了系统级仿真,并通过与传统的SU-MIMO性能比较,得出了联合传输技术在提高边缘用户性能和小区吞吐量方面的优势。

| Abstract: | Coordinate Multipoint transmission and reception （CoMP）, as a promising technology to improve the average cell throughput particularly the cell-edge user throughput, new becomes a research hotspot in LTE-hdvanced system. This paper discusses the down]ink joint transmission based on SU-MIMO （CoMP-SU-MIMO）, analyzes the system model, and proposes the calculation method for user signal to interference plus noise ratio （SINE）. Finally the simu]ation on system level is done, and the comparison with traditional SU-MIMO indicates the advantage of the joint transmission technology in improving edge user performance and cell throughput. |
