VLC-system-employing-an-LDPC-code
- 对提高可见光通信传输速率的研究，并提出了使用LDPC编码来降低干扰。-In order to increase a transmission rate, the transmitter is composed of plural LEDs and sends digital information by independently controlling brightness of them, which is called parallel transmissions. The r
Reducing-Background-Noise-in-VLC
- 对可见光通信中怎样减少背景光干扰的研究，并使用NRZI编码。-We demonstrate that non-return-to-zero-inverted (NRZI) code reduces the background optical interference effectively in low frequency band. The comparison between nonreturn- to-zero (NRZ) code and NRZI code was per
Modulations-for-VLC
- 对可见光通信的调制模块进行研究，并且对各种调制方案的调光功能进行了研究和比较。-we propose a MPPM to offer both functions of modulating data-stream and controlling the brightness at the same time.From our studies, we show that MPPM is superior to variable on–off keying (VOOK) and var
