摘要
基于"通信原理"课程实践教学环节,结合可见光通信技术,提出了一种基于颜色强度键控的编码实验.首先,基于二维平面的4-CSK星座,提出了颜色强度键控的5-CSK星座设计方案.其次,通过设计符号子集划分准则和网格编码结构,提出了最小状态数下两种5-CSK编码实验方案.在此基础上,引入状态分裂方法,进一步提出了高编码增益的4状态下5-CSK编码实验方案.仿真实验表明,所提的三种颜色强度键控编码实验方案具有明显的误码率性能优势.
Abstract
Based on the practical teaching link of the Principles of Communication Technology course,combined with the visible light communication technology,a coding scheme based on color and intensity shift keying is proposed.First,the 5-CSK constellation design scheme based on the two-dimensional(2D)4-CSK constellation is proposed,which uses the color and intensity shift keying.Secondly,the symbol subset splitting criteria and trellis coding structure are designed,and two experimental schemes of 5-CSK coding under the minimum number of states are proposed.On this basis,by introducing state splitting,a 4-state 5-CSK coding experimental scheme with high coding gain is further proposed.The simulation results show that the proposed three color and intensity shift keying coding experimental schemes have obvious bit error rate performance advantages.
