Noise reduction in VLC channels using Wavelet Multiresolution Analysis

This paper seeks to reduce the noise in signals present in a wireless channel using Multiresolution Analysis (MRA). The noise reduction is performed by applying the MRA to signals obtained from a wireless channel such as a VLC (Visible Light Communication) channel. The work is carried out by means of software that allows to apply MRA for the respective noise reduction. The effectiveness of the MRA will depend on the level of signal decomposition, as well as the detail and approximation components that are subsequently used for the reconstruction of the signal itself. The results obtained are favorable in the opinion of the authors. Finally obtaining a significant noise reduction.
