Problems solved by technology

[0004] From the first simulation, although all simulations have improved the accuracy of the results step by step, because only the reflection mode of diffuse reflection is used, and the important part of specular reflection is ignored, the simulation results are inevitably different from the actual situation. a certain degree of error

Embodiment Construction

[0026] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0027] The idea of ​​the present invention is to improve the existing visible light indoor communication channel model. After introducing specular reflection, the reflection mode of specular reflection will be adopted for the light reaching the mirror surface, and one incident ray will only generate one outgoing ray, thus to a certain extent It overcomes the interference caused by multipath effects and does not need to consider the complex problem of diffuse reflection and reflected light, which greatly simplifies the complexity of signal transmission and can also obtain more accurate indoor power distribution.

[0028] A simulation calculation method for indoor visible light power distribution with specular reflection, such as figure 1 Shown: Specifically includes the following steps:

[0029] Step 1, setting the required parameters; the paramete...

Abstract

The invention discloses an indoor visible light power distribution simulation calculation method including specular reflection, which solves the problem that only the diffuse reflection mode is considered in the modeling of the traditional indoor visible light communication channel. The invention mainly converts the traditional reflection mode that only considers the diffuse reflection. In order to consider the reflection method of the combination of diffuse reflection and specular reflection, and give the method used to calculate the specular reflection, it makes up for the shortcomings of incomplete consideration in the traditional channel modeling and simulation process, and is more in line with the actual scene to a certain extent. Enables further optimization of indoor visible light modeling.

Description

technical field [0001] The invention belongs to the technical field of visible light communication, and in particular relates to a method for simulating and calculating indoor visible light power distribution including specular reflection. Background technique [0002] Different from the traditional indoor visible light modeling method that only uses diffuse reflection mode, this modeling method combines diffuse reflection and specular reflection. The reason for this method is one: a mirror will be decorated in many places in the actual scene To achieve the effect of expanding the space; Reason 2: Compared with diffuse reflection, specular reflection can obtain higher power; Reason 3: For specular reflection, an incident ray can only produce one outgoing ray, so it is reflected from a certain point through the wall There is only one route to the other point. Compared with diffuse reflection, the impact of multipath interference can be reduced to a certain extent, so that fas...
