2차원 코딩을 이용한 광학카메라 통신시스템의 성능평가

초록

In this paper, we evaluate the performance of an optical camera communication system (OCC) using two-dimensional coding. This coding method aims to improve the data rate as compared with traditional coding in which the LED array transmits only one signal at a time. We examine two different thresholding methods of signal processing at the receiver, and show that the third-order polynomial thresholding method achieves better performance. Through experiments, it is shown that the data rate on target system can be increased up to 60 kbps
