Description
Summary:	Visible Light Communication technology uses visible light to wirelessly transmit data, providing advantages such as high bandwidth and immunity to electromagnetic interference. With the growing demand for higher data rates, optimizing modulation schemes is crucial. This study focuses on the reduction in Bit Error Rate (BER) achieved by using 256-QAM (Quadrature Amplitude Modulation) compared to 128-QAM in VLC systems. The success rate achieved with 256 QAM is 0.98, compared to 0.96 for QPSK modulation. Implementing the proposed 256 QAM model significantly reduces the Bit Error Rate compared to the 128 QAM model in VLC systems. This advancement towards achieving a lower BER represents a substantial improvement in the overall quality of the system's output.
