摘　　要： 针对因移动通信的迅猛发展使得移动通信系统重新显现的频谱匮乏、容量不足等问题,提出一种基于单天线移动终端的蜂窝链路多入多出(MIMO)容量增强技术,即基于超宽带技术的广义虚拟多入多出(G-VMIMO)结构的应用。文章详细讲述了G-VMIMO结构的原理和特点,并从理论上分析该结构具有MIMO容量增强性能。文章给出了G-VMIMO系统的构成方法和协议流程,并针对系统实现所面临的难点进行了详细探讨。最后,计算机仿真验证了G-VMIMO系统的容量增强性能以及可行性。 A multiple-input-multiple-output （MIMO） capacity enhancement technique of cellular link based on mobile terminal with single antenna was proposed, which was the application of generalized virtual-MIMO architecture based on ultra wide-band （UWB） technique. The principle and benefits of G-VMIMO were detailed. Besides, the capacity enhancement of cellular link based on G-VMIMO was analyzed theoretically. The establishment of G-MIMO system was put forward, and the challenges brought by the practical application of G-VMIMO to the existing cellular networks and wireless personal area network （WPAN） were explored. Finally, computer simulation verifies the capacity enhancement and the validity of G-VMIMO.
