Abstract
In order to further reduce the bit error rate of multi-user multi-cell visible light communication systems using non-or-thogonal multiple access/orthogonal frequency division multiple access(NOMA/OFDMA)technology,a joint power and subcar-rier allocation algorithm is proposed.This algorithm aims to minimize the system's symbol error rate by achieving the joint opti-mal allocation of carrier and user power across sub-cells.Firstly,the symbol error rate expression of the system is theoretically de-rived.Then,Matlab software is used to simulate the visible light communication system model,and the optimal allocation results are obtained through genetic algorithms.Finally,the proposed algorithm is compared with existing algorithms.The simulation re-sults show that the symbol error rate performance of the proposed algorithm is superior.关键词
