In this paper, the effect of different types of filters on the performance of a total least square–based receiver for a visible light communication system is studied. In the literature, the most common type of filter that is used is a matched filter. This is considered to be an optimal filter and it is commonly available. In the computationally limited environment, where there are not enough resources to match the needs of an optimal filter such as matched filter, this paper investigates the use of other potential filters such as Butterworth, elliptical, and Chebyshev filters. This paper also investigates the effect of choosing a suitable transmission band to countermeasure the effects of noise from artificial light sources and sun. The proposed system is analyzed on the parameter of bit error rate.
