摘　　要：从提高可见光通信(VLC)的通信速率和系统的实用性出发,研究了基于八进制幅移键控(8-ASK)调制解调的VLC系统。通过Optisystem和Matlab联合仿真,确定在保证低误码率情况下八进制为多进制调制中的最优进制数。设计了VLC系统发射端、接收端和判决再生电路,进行了8-ASK调制的可见光通信实验研究。实验证明了在保证低误码率的情况下通过该方法提高通信速率的可行性。In order to improve the VLC system communication rate and the practicality of the system, a VLC system based on 8-ASK modulation-demodulation scheme is studied in this paper. In the premise of low bit-error-rate, 8-ASK is determined to be the optimum scale in the multi-scale modulation through the simulation based on Optisystem and Matlab. The transmitter, receiver and decision regeneration circuit are designed and VLC communication experiments based on the 8-ASK modulation are conducted. Results of the experiments show the feasibility of improving the communication rate through this method in the case of low bit-error-rate.
