摘　　要：LTE协议中虽然规定了多种MIMO模式的传输方案,但并没有给出各自的适应环境。为此对各种MIMO模式进行分析仿真验证,得出各自的适应环境具有非常大的意义。主要分析了LTE协议中的三种MIMO传输模式,分别是发射分集、闭环秩为1的空分复用和闭环秩为2的空分复用,经过仿真验证得出了各自的使用环境。LTE protocol provides for a variety of MIMO mode of transmission, but did not give their own adaptation to the en- vironment. Therefore, a variety of MIMO mode simulation, and draw their own adaptation to the environment has a very large sig- nificance. This paper analyzes the LTE protocol 3 M1MO transmission mode, namely, transmit diversity and closed loop with rank 1 space division multiplexing and closed-loop rank 2 space division multiplexing, and the simulation obtained their the use of the en- vironment
