摘要

在室内可见光通信MIMO（多输入多输出）系统中

针对用户无法公平享用通信服务的问题

提出了一种寻找光接收机中最优聚光器增益来优化多用户情况下功率分配不均匀的方法。利用改进的NGA（小生境遗传算法）建立与接收光功率相对应的节点模型

通过运算寻找一组最优的聚光器增益组合运用到光接收系统中。仿真结果表明

改进的NGA能高效地找出一组最优聚光器增益组合

从而改善用户接收光功率分配不均匀的现象。

Abstract

For indoor visible light communication in the MIMO system

users can not enjoy fair communication service issues.In this paper

we propose a method to find the optimal value of the gain of the optical receiver concentrator to solve this problem.It can be used to optimize the multi user power distribution problems.We use an improved niche genetic algorithm establishment and node mode related to the corresponding received optical power to find a set of optimal condenser gain value in the visible light communication system.The simulation results show that the improved niche genetic algorithm performs can find a set of optimum condenser efficiently

and improve the service quality of indoor visible light communication system.
