Design of Experimental on Color and Intensity Shift Keying Based on Visible Light Communication
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.
