| 摘 要： | 根据室内物体对电波的反射和透射的特点，结合射线跟踪法，提出了一种室内物体的分块模型；考虑不同物体介电特性的差别，建立了能存储物体各种参数的数据库；设计了射线跟踪的递归算法，据此计算出室内各处电波传播的路径损耗．对一室内环境进行实地测量，计算结果与测量结果吻合较好．

| Abstract: | Propagation prediction is im portantfor designing indoor wireless com m unication system s. Ray tracing is a usefultoolfor propagation prediction. By using the features of reflection and refraction by indoor objects, a patched m odelcom bined w ith the ray tracing technique was presented. The dielectric difference ofdifferentobstacle w asconsidered. The software thatgivesthe path lossofany siteinside the building w as also developed. The calculation results agree wellwith the m easurem ent. |
