摘要 将虚拟MIMO技术引入到自组织多跳无线网络中,可显著提高系统容量。而发挥虚拟MIMO优势的关键之处在于,根据通信需要建立合理的虚拟天线阵列小区。目前相关领域的研究还没涉及小区的建立机制,因此急需提出或改进现有的方法和算法来选取小区的划分机制。基于这种需求,从通信性能主要指标的角度出发,针对虚拟天线阵列小区划分,进行了理论分析建模,提出了两种初步划分小区的方案,并分别针对功率、容量、时延等指标进行考察,同时利用MATLAB进行数值仿真。结果表明,小区划分机制依赖于具体的应用。 Capacity of systems can be improved when virtual MIMO scheme is applied in the wireless self-organized multihop network. The key to make full use of virtual MIMO's advantages is to deploy the rational virtual antenna arrays according to actual conditions, but at present, there are few researches related with it. So it is necessary to bring forward new methods or improve previous methods for constructing virtual antenna arrays. Based on the main targets of communication performance, a model of forming virtual antenna array group was built, and two solutions for constructing virtual antenna arrays were proposed. At the same time, the power, capability and delay were surveyed, and the simulation was completed by MATLAB. Simulation results show that the solution for constructing virtual antenna arrays depends on the actual applications.
