摘　　要：在虚拟多输入多输出(Virtual Multi-Input Multi-Output,V-MIMO)系统中,怎样通过一定的准则来选择出合适的用户并对其进行配对是该技术的关键问题。为了提升虚拟MIMO系统容量并兼顾公平,文中在分析了传统虚拟MIMO用户配对算法的基础上,对一种基于双比例公平准则的配对算法进行了优化。该优化算法通过分组调度把用户分为两组,结合双比例公平分别在两组内挑选用户进行配对。仿真结果表明,优化后的算法比传统算法在保证系统容量的同时,提升了公平性。How to select and match the appropriate users through certain criteria is the core problem of the V-MIMO(Virtual Multi-Input Multi-Output)system.In order to improve the capacity of V-MIMO system and consider fairness,based on the analysis of traditional V-MIMO user pairing algorithm,a double proportional fairness criterion matching algorithm is optimized.The optimization algorithm divides users into two groups through group scheduling,and selects users in two groups to perform pairing in combination with double proportional fairness.The simulation results show that the optimized algorithm improves the fairness while ensuring the system capacity.
