Performance Analysis of Underground Mines Visible Light Communication in Various Modulation

This study examined the performance of visible light communication (VLC) in underground mines using LOS and NLOS channel models and various modulations, including OOK-RZ, OOK-NRZ, 8-PPM, and 8-PAM. Based on the simulation results, the SNR value in the NLOS channel model is 9.194 dB, while in the LOS...

Description
Summary:	This study examined the performance of visible light communication (VLC) in underground mines using LOS and NLOS channel models and various modulations, including OOK-RZ, OOK-NRZ, 8-PPM, and 8-PAM. Based on the simulation results, the SNR value in the NLOS channel model is 9.194 dB, while in the LOS channel, it is about 21.169 dB at a distance of 8.52 meters. For each modulation, the BER simulation gave different values. BER 8-PPM, OOK-RZ, and OOK-NRZ provided good results for the LOS channel model at a distance of 8.52 meters, with values below threshold. Meanwhile, 8-PAM had a maximum distance of 7.06 meters. For the NLOS channel model, only 8-PPM could reach a maximum distance of 8.52 meters. OOK-RZ could reach the maximum distance at 8.03 meters. OOK-NRZ could reach the maximum distance at 7.06 meters. 8-PAM had the highest BER value at a maximum distance of 5.22 meters. Based on this research, the use of an 8-PPM modulation scheme could improve the transmission efficiency of VLC in an underground mining environment. The results of this study can help in improving the development of reliable VLC systems for underground mines.
