二维非均匀散射信道改进模型

提出了一种基于谐波信号叠加的二维非均匀散射信道改进模型，分析并给出了基于信号入射角概率面积等分的参数计算方法。该方案可完成任意接收信号入射角一维概率分布已知的单径散射信道仿真，且易于采用分段仿真的思想提高各阶统计参量的性能或实现多径信道仿真。分析和仿真结果表明，新模型的信道自相关函数、多普勒功率谱等二阶统计参量与理论模型十分接近，且优于其他常见模型。

Improved channel model under 2D non-isotropic scattering conditions

A modified sum-of-sinusoids (SoS) channel model for two-dimensional (2D) non-isotropic scattering conditions is proposed. With the new parameter computation method, called equal probability areas (MEPA) of the angle of arrival (AoA), it can be applied on any single-path channel simulation with given distribution of AoA.It is also easy to use the principle of set partitioning to improve the performance or simulate multi-path channels. Analysis and simulation results demonstrate that the auto-correlation function, Doppler power spectrum and other second order statistics of the new model are close to the theory model, and better than other models.
