摘要:

本文提出了一种基于WINNER+信道模型的三维(3-D)非平稳宽带多输入多输出(MIMO)信道模型。该模型联合考虑了簇在水平面和垂直面上的角度分布。接收端和簇均可以移动,这使得模型更具一般性。簇数量、功率、时延、离开方位角(AAoD)、到达方位角(AAoA)、离开俯仰角(EAoD)和到达俯仰角(EAoA)等参数都是时变的。簇的时间演化采用生灭过程进行建模。本文研究并分析了统计特性,包括空间互相关函数(CCF)、时间自相关函数(ACF)、多普勒功率谱密度(PSD)、电平通过率(LCR)、平均衰落持续时间(AFD)和平稳区间。所提信道模型的LCR、AFD和平稳区间通过实测数据进行了验证。数值和仿真结果表明,所提出的信道模型能够再现真实非平稳信道的主要特性。此外,通过调整不同的参数值,所提出的信道模型可以适用于各种通信场景。

英文摘要:

In this paper, a three-dimensional (3-D) non-stationary wideband multiple-input multiple-output (MIMO) channel model based on the WINNER+ channel model is proposed. The angular distributions of clusters in both the horizontal and vertical planes are jointly considered. The receiver and clusters can be moving, which makes the model more general. Parameters including number of clusters, powers, delays, azimuth angles of departure (AAoDs), azimuth angles of arrival (AAoAs), elevation angles of departure (EAoDs), and elevation angles of arrival (EAoAs) are time-variant. The cluster time evolution is modeled using a birth-death process. Statistical properties, including spatial cross-correlation function (CCF), temporal autocorrelation function (ACF), Doppler power spectrum density (PSD), level-crossing rate (LCR), average fading duration (AFD), and stationary interval are investigated and analyzed. The LCR, AFD, and stationary interval of the proposed channel model are validated against the measurement data. Numerical and simulation results show that the proposed channel model has the ability to reproduce the main properties of real non-stationary channels. Furthermore, the proposed channel model can be adapted to various communication scenarios by adjusting different parameter values.
