Abstract

The solution for mobile phone users and the need for high-speed data services that meets the traffic requirements of existing 4G networks, 5G networks have become the core technology and implementation technology for nextgeneration communication networks. A MIMO-OFDM, a fully generalized LED modulation system is proposed for VLC communications. LED signals are used in innovative ways as well as OFDM signal time/frequency field formation issues to improve the efficient spectrum (SE). The analytical investigation and experimental demonstration of the proposed ACOOFDM for massive MIMO internal systems has been performed. Moreover, the traditional OFDM performance is examined in this comparison system. The results of the analysis showed that massive MIMO-VLC that uses ACO-OFDM show less computational complexity on comparison than systems that use OFDM. Finally, the results show that this scheme can achieve better energy efficiency and spectrum performance with acceptable BER performance compared to related methods.
