摘要

基于2.55 GHz城市微蜂窝场景多输入多输出(MIMO

multiple-input multiple-output)信道实测数据，研究了三维宽带无线信道的时变特性，利用SAGE (space-alternating generalized expectation-maximization)算法提取多径参数，包括水平、垂直面的电波离开角和电波到达角，采用双向匹配算法识别并跟踪多径，建立了多径的“生灭”模型，统计分析了多径的出现率、多径生命周期、多径初始参数和演进参数等时变信道模型参数并根据上述参数的统计分布和相关性展开建模，建立了基于多径“生灭”过程的时变信道模型，并给出了详细的模型参数和仿真实现步骤，通过对比实测数据和仿真结果的均方根时延扩展和均方根角度扩展，验证了模型的可用性。提出的时变信道模型可用于城市微蜂窝场景时变信道仿真，也为5G动态信道建模的研究提供重要参考。

Abstract

Based on the outdoor microcell MIMO channel measurement campaign at 2.55 GHz

the time-evolution characteristics of three-dimensional wideband channel were studied.The SAGE algorithm was used to extract multipath parameters such as azimuth and elevation angle of departure and arrival.A bidirectional matching algorithm was applied to tracing multipath and the ＆quot;birth-death＆quot; process.The statistical characteristics of multipath birth

lifespan

multipath initial and evolution parameters were analyzed and modeled based on the cross-correlations of multipath parameters.A time-varying channel model with multipath birth-death process was developed.The model parameter table and a detailed flowchart were offered for time-varying channel simulations.The proposed model was validated by comparing the root-mean-square (RMS) of delay spread and angular spread between the simulated and measured results.The channel model proposed can be applied in time-varying channel simulation for urban microcells and it’s also very important to be referred in 5G dynamic channel modeling.
