This paper reports the experimental evaluation of the On-Off Keying (OOK) modulation technique for a non-directed 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.
