摘　　要：文章采用基于定点的迭代模型对非定向信道进行分析,得出了具体的迭代公式。在有家具的房间环境中,给出了可视光的增益公式,通过MATLAB编程实现了反射次数k=0、1、2三种情况下的脉冲响应,给出了仿真图形并加以说明。同时又对空房间的三种情况下的脉冲响应进行了仿真,通过与有家具的环境的比较,得出了随房间高度增加,非可视分量也增加的结论。Analysis is made of non-directional channels by using site-based iterative modeling, thus obtaining the specific iterative formula. For rooms with furniture, the optical gain formula of LOS is presented. Impulse responses when reflection times k = 0, 1, 2 are simulated by MATLAB programming and the simulation graphics given and explained. In addition, the impulse responses for rooms without furniture in the same conditions are also simulated and compared with those for rooms with furniture, leading to the conclusion that the non-LOS components increase along with the height of the rooms.
