| Abstract: | In this paper,the PAM-DMT technique is used in the white light LED communication system,proposed the thought of combining time-domain window technique and PAM-DMT,and cyclic prefix/suffix is also added to the system.Finally,simulated the performance of the system based on Matlab.The result shows this technique can improve multipath suppression,spectral efficiency and BER of system. |
