dc.description.abstractVisible light communication (VLC) is secured and high-speed communication for a specified area location. This provides a green-fuzzy technology for optical wireless communication system design. The VLC channel included different parameters, where the variation of the parameter can be analyzed from different channel estimation techniques. The VLC channel is affected by both static and mobile environments. Previously most of the research is on static VLC channels but recently mobile VLC communication is in trend and has more applications in the real world. Thermal noise, ambient noise, shot noise, the distance of the transceiver, and the position of the receiver are some parameters, which has caused a major effect on the VLC Channel estimation system. So many estimation techniques for VLC channels are available to estimate the performance of communication links. In this paper, a detailed comparative analysis is given for both DC-biased optical orthogonal frequency division multiplexing (DCO-OFDM) and asymmetrically clipped orthogonal frequency division multiplexing (ACO-OFDM). Here, a novel VLC channel estimation technique for multiple-inputmultiple-output (MIMO) ACO-OFDM is designed, where the performance of linear minimum mean square error (LMMSE) channel estimation technique can be concluded with the bit error rate (BER) response. The paper considers least square (LS) and LMMSE channel estimation techniques to compare the proposed work with the verified worken_US
