Abstract
We propose a Z-HBT line coding for a LED-ID system. Z-HBT line coding is defined as follows. First, we apply half bit transition to one bit. Second, we decode encoded bits using difference of bit transition level in one bit duration. As a result, we obtain advantages about synchronization problem and noise effect mitigation at the receiver. We set up outdoor the LED-ID simulation environment. At simulation results, we show 2-3dB gain as compared with existing line coding schemes. The results of the paper can be applied to design and implementation of LED-ID systems for indoor wireless multimedia services.
