摘要
针对可见光多载波通信系统传输速率低、帧间干扰大的问题,采用改进的樽海鞘群算法对可见光多载波通信系统的调制器算法进行优化,以提高可见光通信的数据传输速率。该文详细分析了可见光通信系统的多载波调制器,全面考虑了相关调制系统的重要参数集,并给出合理的质量评价函数。将布谷鸟搜索算子引入樽海鞘群算法以增强其全局搜索能力,最终利用改进的樽海鞘群算法对可见光通信多载波调制器做优化。仿真实验结果表明,运用樽海鞘群算法能够对可见光通信多载波调制系统的参数进行优化,提高可见光通信的传输速率。
The existing visible light multi-carrier communication systems suffers low transmission rate and critical inter-frame interference, the Salp Swarm Algorithm is taken advantage of to optimize the modulation module algorithm of visible light multi-carrier communication systems, in order to increase the data transmission rate of visible light communication. The characteristics of multi-carrier modulation of visible light communication system is analyzed in detail, and comprehensively considers the important parameters of relative modulation systems, it also presents a reasonable quality evaluation function. The exploration operation of Cuckoo Search is introduced the into Salp Swarm Algorithm to enhance the global search power of that algorithm, finally the improved Salp Swarm Algorithm is taken advantage to optimize the multi-carrier modulation module of visible light communication systems. Simulation experimental results show that the parameters of visible light communication multi-carrier modulation can be optimized with the Salp swarm algorithm, and the transmission speed of the visible light communication increases effectively.
