Investigation of channel state information conditions in VL-NOMA using power allocation technique for 6G network

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