Hybrid MIMO-OFDM System for 5G Network Using VLC-A Review

The 5G mobile network promises to be faster and smarter and has lower latency and higher efficiency, lower bandwidth issues compared to 4G. A VLC uses LED for higher data transfer rate wireless communication. Wireless standards in broadband system LTE (Long Term Evolution) and MIMO (Multiple-Input-Multiple-Output) Wi-Fi technology incorporate an increase in antennas create more signal path which increases reliability and performance. This paper reviews the performance of VLC usage for the 5G network using MIMO-OFDM, Massive MIMO, SU (Single-user) MIMO, MU (Multi-user)MIMO and Hybrid MIMO which are optimised using various algorithms and presents a comparison of the techniques as mentioned above.
