| 摘 要： | 为了对先进的长期演进技术(long term evolution-advanced,LTE-Advanced)系统中的多输入多输出(multiple input and multiple output,MIMO)技术的性能进行评估,简单回顾了LTE-Advanced系统中的2种MIMO技术,即空间复用和空间分集,并介绍了一种适合LTE-Advanced系统评估的信道模型--IMT-Advanced(international mobile telecommunications-advanced)信道模型.基于该信道模型,通过系统仿真对以上2种关键MIMO技术进行了性能评估.仿真结果表明,不同的MIMO技术、调制方式、码本、复用率及接收方案都对性能有极大的影响.

| Abstract: | In order to evaluate the performance of multiple input and multiple output (MIMO) technology for long term evolution-advanced (LTE-Advanced) system, this paper makes a brief review of the two MIMO technologies, namely diversity and multiplexing, and introduces a reasonable channel model for LTE-Advanced system, namely the ITU-R IMT-Advanced channel model. Based on this channel model, the performance of these two MIMO technologies for LTE-Advanced system was evaluated by simulation. Simulation results show that the different MIMO techniques, modulation, codebook, multiplexing and receive-scheme have a great impact on performance. |
