Realization of indoor visible light communication system based on V-MPAPM

针对可见光通信中可变脉冲幅度位置调制(VPAPM)方法进行了改进,提出了一种可变多脉冲幅度位置调制(V-MPAPM)方法,在提升通信速率的同时还能提高调光分辨率。在单片机平台上实现了采用V-MPAPM调制的可见光通信系统实验样机。在室内实验场景下进行了系统误码性能及调光性能的测试,验证了该调制技术的可行性。

Aiming at the improvement of variable pulse amplitude position modulation（VPAPM） scheme used for visible light communication（VLC）, a method of variable multi-pulse amplitude position modulation（V-MPAPM） is proposed to increase the data rate and dimming resolution. The experimental prototype of visible light communication system with V-MPAPM modulation is realized on the single chip microcomputer platform. The performance test of bit error rate and dimming resolution are performed under the laboratory experiment conditions to verify the feasibility of this modulation technique.
