Simulation and Analysis of the Adaptive Power Control System on NOMA VLC

Radiofrequency technology is a commonly used technology. This technology has the disadvantage of not being able to cover the increase in data rate services, especially in terms of 5G technology. Visible Light Communication (VLC), a subset of optical communication systems, can potentially be a solution or even a replacement for radio frequency technology. VLC has various Multiple Access Techniques, one of which is non-orthogonal multiple access, commonly called NOMA. In optical communication, the signal transmitted through the communication channel will always experience changes due to interference from outside and customers who are always moving and sometimes away from the transmitter. As a counterbalance to this, Power Control Techniques are used to overcome the problems that often occur. Simulation with Adaptive Power Control will go beyond the power ratio allocation scheme, fixed power allocation scheme, and Multiple Access schemes regarding time-sharing. Or in other words, the results achieved can improve energy efficiency in the system. The research in this final project shows that the number and location of users in the NOMA VLC Adaptive Power Control technique affect the average value data rate and the average gain value achieved. This study also proves that the value of Adaptive Power Control has an important role in changing the gain value. With Adaptive Power Control, the gain has a value of 60% more efficient in its use
