Relay-assisted OFDM transmission for indoor visible light communication

KIZILIRMAK, Refik Çağlar | UYSAL, Murat

In this study, we investigate a relay-assisted visible light communication (VLC) system where an intermediate light source cooperates with the main light source. Specifically, we consider two light sources in an office space; one is the information source employed on the ceiling and the other one is a task light mounted on a desk. Our system builds upon DC biased optical orthogonal frequency division multiplexing (DCO-OFDM). The task light performs amplify-and-forward relaying to assist the communication and operates in half-duplex mode. We investigate the error rate performance of the propose ...Daha fazlası

Turkish Sign Language Animation with Motion Capture

SÖYLEV, Arda | MENDİ, Engin

In this paper, using motion capture, we study on Turkish Sign Language Animation. A markerless system, Microsoft Kinect sensor and a professional optical system are compared. Besides, we use the motion capture data in two different approaches; data driven and real time. To animate the sign language, we merge the motion capture output with a cartoon character. In the first approach, which is data-driven, motion capture data is recorded, processed and converted to a character animation off-line. This data is stored in a database and it can be used in mobile devices or any other necessary ways. R ...Daha fazlası
