| 摘 要： | 由于空间相关特性的影响,限制了多入多出(MIMO)通信系统的应用.参考统一信道分解(UCD)的信道参数反馈方法,提出了一种自适应MIMO系统.这种系统能适用于各种空间相特性.通过仿真验证了基于UCD的MIMO系统在各种空间相关特性下的性能,并讨论了反馈误差对系统性能的影响.

| Abstract: | The application of Multiple Input Multiple Output(MIMO) communication systems is limited because of the effects of spatial correlations.In this paper,a novel adaptive MIMO system is proposed based on uniform channel decomposition(UCD),which can be used for any spatial correlated channel.Simulation demonstrates the performances of UCD-based MIMO system under different spatial conditions,and effect of feedback errors on system performance is discussed,too. |
