摘　　要：在以往组播广播单频网(MBSFN)性能分析中,通常采用系统级仿真器或是实际部署MBSFN网络的方法,但两种方法都复杂并且代价高。在建立一个全新MBSFN系统数学模型基础上,引入MBSFN评价性能指标,最后采用建立的模型对MBSFN性能进行了评估,取得了与系统级仿真相一致的结果,证明了该模型对MBSFN的规划具有一定指导意义。In traditional can be both complex and measures are introduced, system simulator. So it is analysis of MBSFN performances, a system simulator or deploying a real MBSFN network is used, which expensive. In this paper, a novel analytical model of system is proposed firstly, then the performance At last, MBSFN is evaluated by utilizing proposed model. Results are inline with the findings from helpful for MBSFN planning by using this model.
