Abstract
Fiber systems for transmitting millimeter wave (MMW) signals have recently become increasingly popular for upcoming wireless communication applications, including 5G and beyond networks. This study into the developments in the combination of wireless and optical networks, this paper utilizes this combination and reduces the symbol error rate (SER). The proposed system employs a 4x4 Multi-Input Multiple-Output (MIMO) wireless signal; MIMO can be utilized to improve coverage and increase capacity through spatial multiplexing. MIMO systems are an essential component of today’s wireless networks, and they have been widely utilized in recent times to achieve great spectrum and energy efficiency. In this paper, the 4X4 MIMO is used to support the transmission link and increase throughput. Then, the subcarrier is modulated with a millimeter-wave using a Match Zender Modulator (MZM). The signal is transmitted through a (45-50-75) kilometer optical fiber, thus enhancing the capacity and frequency and increasing errors. The proposed system mitigates this error by utilizing multiple compensator that offset the SER. The VPIphotonics software program and Python are used.
