ICUFN-2012
- The performance of a visible light communication system is greatly affected by LED layout setting. Received power and SNR can be increased or decreased by changing LED placement. However, there is trade-off between received power and SNR. This makes
ICUFN-Receiver-Power-and-SNR-optimization-for-Vis
- The performance of a visible light communication system is greatly affected by LED layout setting. Received power and SNR can be increased or decreased by changing LED placement. However, there is trade-off between received power and SNR. This makes
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
VLC-using-OFDM
- 将OFDM技术运用在可见光通信的研究，并且把OFDM的高峰均比这一缺点进行了建设性的运用。-In particular, the use of OFDM (orthogonal frequency division multiplexing) for intensity modulation is investigated. The high peak-to-average ratio (PAR) in OFDM is usually considered a disadvant

- 代码描述了可见光通信中关于光源分布的情况，不同光源分布造成屋内各个位置信噪比不同，上传了一个光源分布中心的，八个光源形成圆形分布以及最佳光源最佳分布类型。-Code describes the visible light communication information on the distribution of different light distribution caused by different house each location SNR uploaded a light
H_264
- 针对多媒体视频传输的安全性与实时性的要求, 提出一种基于H.264 感知加密算法的视 频加密方案。该方案将视频数据分为VLC(Variable Length Code) 和FLC（Fix-Length Code ）两类，只选择 FLC 中对重构图像比较重要的元素进行加密操作。理论分析和仿真结果表明，该加密方案具有安全性 高，低成本系统开销的特性。-To meet the requirement of multimedia video transmission s safety and
