LEDs are expected as lightning sources for next generation, and data transmission system using LEDs attract attention.
In this paper, we present hierarchical coding scheme using LED traffic lights and high-speed camera for Intelligent Transport Systems (ITS) application.
Further, if each of LEDs in traffic lights is individually modulated, parallel data transmissions are possible using a camera as a reception device.
Such parallel LED-camera channel can be modeled as spatial low-pass filtered channel of which the cut-off frequency varies according to the distance.
To overcome, we propose hierarchical coding scheme based on 2D fast Haar wavelet transform. |
