| Summary: | 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. |
