摘要
介绍IEEE 802.11n室内信道(TGn)的模型组成和相关概念,以"簇"结构为基础,使用数学模型分析说明信道的建模流程,依次讨论了该信道模型的大尺度、小尺度衰落以及空间相关特性。以TGn信道D为例,使用maltab建立信道仿真模型,简单介绍仿真流程,并对生成的信道数据的相关时间、相关带宽、多径以及包络等信道参数进行验证,验证结果与信道参数相符,为后续使用多径信道验证OFDM物理层信号处理算法性能提供基础。
Firstly the components and concepts of TGn channel model are described, and based on cluster structure, the channel modeling process is described with mathematical method, including large scale and small scale fading, spatial correlation characteristics. Simulation model is established with Matlab and a brief introduction of the simulation process is given in the paper. In addition, the verifications on correla- tion tittle, bandwidth, multipath and envelope of the channel are done, and the verification results and channel parameters are well-matched, and these would provide a foundation for later research on the performance of OFDM physical-layer signal processing algorithm under multiple channel.
