摘要

摘要：将多径分量仿真为随机射线的传播，其轨迹描述为随机桥过程的样本。研究随机射线在渗流网格中扩散的物理规律，以改进物理散射约束，使之有足够样本用于场强时延分布建模。通过实验，模拟不同波长的波束在不同散射体密度的渗流网格内的扩散，得出信道的相干带宽、误码率和场强的统计特征，验证了信号的多径衰落统计特征与相应的随机射线扩散程度有关，随机射线模型能够较大概率地仿真信号多径衰落的特性。

Abstract

The propagating stochastic rays were employed to simulated multi-path components（MPC）

which tracks were represented by samples of stochastic bridge processes. The laws of physics about stochastic ray diffusing in percolation lattices were studied to improve constraints of physical diffusion

which made it with enough samples to model power delay probability. According to experimental

different wavelengths of beam were simulated to diffuse in percolation lattices with different scatters density. Coherence bandwidths

bit error rate and statistics characteristics of power were acquired to verify that stochastic ray model can fit to the characteristics of the multi-path fading channel

which can predict channel parameters in specific locations.
