Abstract

This paper investigates the channel state information (CSI) conditions in visible light non-orthogonal multiple access (VL-NOMA) using the power allocation technique (PA) for a sixth-generation (6G) network. One light-emitting diode (LED) is used as a carrier to transmit the signal to three-user-positioned at certain distances. The challenge of allocating power to the system is solved using the PA technique. The PA technique uses to assign signal powers to the three users. The VL-NOMA channel with CSI symbols is synchronized for the performance of signal propagation. We deployed perfect CSI, imperfect CSI, and partial CSI to coordinate the signal enhancement that results in an improved data rate, higher channel capacity, and improved signal-to-noise ratio (SNR). The synchronized system model guarantees successful signal enhancement where perfect CSI performs better than partial CSI and imperfect CSI. We have enabled interference plus noise to see how the system behaves. We notice low channel capacity region, low data rate performance, etc. Hence, we analyse the PA to determine the outage probability effect on the signal.
