了解可見光通信有哪些好的paper值得一看？

---

日本可見光通訊協會組織的2015年會，這個領域這麼多年沒有發展起來以我所知這是本領域比較像樣的會議了，似乎只有兩個section總共八篇論文，由於智能手機攝像頭的普及optical camera communications光學攝像頭通訊OCC在這次會議上非常受到重視cover了大半討論內容。會議的keynotes演講比較值得看，

• Intel介紹了領域本領域的歷史與動態，尤其是本家工作基於常規採樣率攝像頭的欠採樣頻移開關健控Undersampled frequency shift ON-OFF keying (UFSOOK)，Richard D. Roberts, Intel Corporation, USA 「Kick Starting the VLC Market via Optical Camera Communications」 ： 2015_10_26_RobertsICEVLC2015CC, 2015_10_26_RobertsSlidesICEVLC2015CC
• CASIO介紹在圖像感測器上進行可見光通訊的工作，Nobuo Iizuka, Casio Computer Co., Ltd., Japan 「Image Sensor Communication – Evolution, Now and Future-」 : 2015_10_26_CasioIizukaICEVLC2015cCC

截幾個圖

Intel的報告技術部分著重介紹欠採樣頻移開關健控UFSOOK -

CASIO的報告技術部分主要介紹自家信道空分復用的Picalico -

另外

• 韓國的Kookmin University進行了比較深入的IEEE 802.15.7r1標準介紹，
• 德國Fraunhofer Heinrich Hertz Institute介紹了他們的超高速可見光通訊模組。

國內復旦的組有帶論文參加，中科大的一位老師是程序委員，港理工和台灣的老師有合作論文發表。

要問我為什麼會來回答這樣一個問題，很久以前在大學時候因為偶然的想法做過熒光燈上的（那時候遠沒有現在這樣LED照明滿大街並且熒光燈上的通訊比LED難不少）可見光通訊，並且構想了室內定位應用搭建了原型系統。智能手機興起的時候有朋友提起過有可能實現用攝像頭的光通訊，前段時間思考肯定有欠採樣類似UFSOOK這樣的方法，剛剛看日經BP的新聞注意到相關的會議果然發現這個會議是個很好總結 -

另外一點有意思的材料

[802SEC] CALL FOR APPLICATIONS on Optical Camera Communications (Jan. Me

The following is a list of some optical camera communications characteristics which may be leveraged in a particular application.

- The receiver may be an image sensor associated with a camera. The objective is to enable the reception of data modulated light without making any hardware modifications to the camera enabled platform.

- The light sources may be multi-colored, uni-colored or white.

- The lens associated with the camera may offer spatial separation of light sources that opens up the possibility of doing MIMO data transmissions.

- There have been a number of optical camera communications demonstrations uploaded to YouTube, using different modulation and detection methods, as listed below.

a) Under-sampled Frequency Shifted ON-OFF Keying (UFSOOK) (Intel Labs) http://www.youtube.com/watch?v=K0xsZqTRXesb) Nyquist Sampled Picapicamera (Casio) http://www.youtube.com/watch?v=t27x1sztArEc) Rolling Shutter Sampling (PureVLC) http://www.youtube.com/watch?v=IaxD4SF3jsA
