Clipping Distortions Mitigations and Comparison of BPSK-DCO-OFDM with OOK-DCO-OFDM in Visible Light Communication

In order to reduce the number of clipping distortions that occur in visible light communication, the purpose of this research is to examine the similarities and differences between BPSK, OOK, and DC-biased Optical Orthogonal Frequency Division Multiplexing. Twenty people were sampled, and data transfer frequency determined the minimum distortion. Two clipping distortion groups are considered: BPSK with 20 samples and OOK with 20 samples. G-power of 0.8, alpha and beta values of 0.05 and 0.2, and a confidence range of 95% were used to compute. BPSK has an 86.31 percent success rate, whereas On-off Keying modulation has 90.96 percent. The significance level is 0.001 (p<0.05). There are statistically significant disparities between groups. Regarding the performance study of Signal using DCO-OFDM in visible light Communication, the suggested BPSK model obtains a lower level of clipping distortions or sounds compared to the OOK model. As a consequence, if the sounds present either inside or outside are dampened, then it indicates that the signal may be broadcast and received precisely.
