Abstract

This letter reports the experimental evaluation of the on-off keying (OOK) modulation technique for a nondirected line-of-sight (LOS) infrared optical wireless communication (OWC) link. Performance evaluation is carried out in a typical room environment in the presence of fluorescent light driven by an electronic ballast. The adverse effect of the fluorescent light inference (FLI) is demonstrated and a number of mitigating techniques including high pass filtering (HPF) and discrete wavelet transform (DWT)-based denoising are investigated. The study shows that DWT outperforms HPF for all data rates. The practical measurements are also verified using a computer simulation.
