摘要
以LTE(long term evolution)-Advanced系统为背景,针对单用户MIMO(multi-input multi-output)技术中的空间复用和空间分集,以IMT-Advanced信道模型为基础,在不同的无线场景和不同的调制方式下,对其误码性能进行了深入的数值仿真分析,并结合无线通信场景的特点,对2种MIMO技术的环境适应性进行了评估和分析。分析结果表明,不同无线场景对空间复用/空间分集技术的性能影响不尽相同。
In the background of LTE-Advanced, based on the single-user MIMO spatial multiplexing technology and space diversity of IMT-Advanced channel model, simulation analysis is done to the bit error rate performance in-depth in different wireless scenarios and different modulation modes. And combining with wireless communication features of the scene, we can get the conclusion： spatial multiplexing/spatial diversity technology performance is not the same in different wireless scenarios. The conclusion has a certain reference value about the actual design for LTE-Advanced system.
