摘要: 针对宽带的MIMO信道建模问题,提出一种通用多天线信道模型及其构造方法.该方法把克罗内克积应用到频域,同时提出频域散射衰落加权因子的概念,由此导出一种室外宽带MIMO散射分布模型.经过简化,该模型还可以应用到室内场景.仿真结果表明,这种通用信道模型能够准确的描述出宽带MIMO信道的视距(LoS)、非视距(NLoS)、室内外散射特征以及孔径效应.

Abstract: A generalized multi-antenna channel model and generating process are proposed for the broadband MIMO channel.By introducing the Kronecker product into the frequency domain and employing the concept of scattering fading weight factor,an outdoor broadband MIMO scattering-distribution model is derived.With simplification,this model can also be applied to indoor scenario.Simulation results show that this model well describes the LoS,NLoS,indoor,and outdoor scattering properties of broadband MIMO channel as well as the keyhole effect.

Key words: MIMO, channel model, broadband channel, Kronecker product
