摘要: 针对现有室内光无线通信系统中光源设计方案在提供无线信号覆盖均匀性及商用实现上的不足,提出了分布式的光源设计改进方案。通过增加LED阵列的分组数目,以分组为单位增加光源的均匀分布程度,给出了两种具体的分布式设计方案。仿真结果表明,在使用LED芯片数量保持相等的基础上,分布式方案比传统方案具有更高的无线信号覆盖均匀性、更低的商用实现复杂度,同时能够彻底避免覆盖低谷。

Abstract: The existing indoor optical wireless communication systems can not provide good wireless coverage uniformity and are not suitable for commercial applications. Two distributed light design schemes were proposed to solve the above problems, which increased the group number of LED array, and then increased the uniformity of light distribution of every group. The simulation results indicate that with the same number of LED chips, the distributed light design scheme is superior to the traditional one in uniformity of wireless signal coverage and complexity of commercial implementation, and can avoid the coverage valley.
