射线追踪技术在无线信道仿真中的研究与实现

his paper studies the application and implementation of Ray-Tracing technology in wireless channel simulation. The wireless channel can be modeled as the collection of electromagnetic rays, including direct rays, reflection rays, transmission rays and diffraction rays. Assumes the emission source is a point, and uses icosahedron to simulate the emission electromagnetic rays. The rays' attenuation can be calculated in accordance with the Reflection Theorem, Transmission Theorem and the Uniform Theory of Diffraction. Sets up several adjacent squares which called receiving Bins, combines each Bin's field strength, and then can get the distribution of wireless signal strength. The realization of it can help do research of propagation in wireless channels and instruct the wireless network planning and optimization.
