有关于通信系统中呼损率随切换指标的变化规律，可以判决接入指标-Call on the communication system to switch targets with the loss rate of change in the law can impose access indicators

】3GPP LTE是基于OFDM和MIMO技术对当前3G系统的中长期演进，对现有的3G系统的网络结构和无线接入方 式都有较大的改进。 文章详细分析了3GPP LTE所规范的切换过程， 并对各大厂商提出的移动终端接入目标基站的几种方法 （同 步和非同步）做了比较性研究。-3G LTE based on the technology of OFDM and MIMO is the long term evolution of 3G system , and it has made gr

系统级仿真，LTE网络，切换、性能、掉话等分析。(System level simulation, LTE network, switching, performance, drop calls and other analysis.)
