Abstract :
In this paper, an optical wireless communication system that uses white LEDs is described. Equalization is employed at the receiver to improve the data rate. Simulation shows a highly reliable communication channel with an SNR of up to 81 dB. Moreover, the data rate can be improved from 16 Mb/s to 32 Mb/s NRZ-OOK at a BER of 10-6.
