Abstract :
A new form of optical wireless communication is presented in this paper. The proposed method is developed from a cheap and simple technology of two dimensional barcode where the data is easily obtained just by using a camera equipped smart phone. In this paper, a computer monitor is used for displaying spatial modulation images and a webcamera is used as a receiver. Consequently, the acquired images are decoded by an in-house software. The encoding process is done by applying the 2D barcode scheme. Initial experimentations are preformed to prove the concept of the method.
