Abstract

Current and future trends in broadband communication, particularly for 5G mobile applications, will include Orthogonal Frequency Division Multiplexing (OFDM) into Radio over Fiber (RoF) technology. Its resistance to multipath fading and spectrum efficiency have made Orthogonal Frequency Division Multiplexing a well-known technique. Network spectrum efficiency has been achieved using the modulation format in optical and wireless communication systems. After that, a system was proposed in which four 18Gbps QAM (Quadrature Amplitude Modulation) signals were generated in each transmitter and modulated in continuous wave (CW) using Mach Zehnder Modulator (MZM) before being transmitted over Single Mode Fiber (SMF), which performs significantly high data rates and is cost-effective in accordance with the results modelled.

光纤无线电(RoF)系统正交频分复用信号处理的实验方法

宽带通信的当前和未来趋势，特别是5G移动应用，将包括正交频分复用(OFDM)到光纤无线电(RoF)技术。它的抗多径衰落和频谱效率使正交频分复用技术成为一种众所周知的技术。在光通信和无线通信系统中，采用调制格式可以提高网络频谱效率。在此基础上，提出了一个系统，在每个发射机中产生4个18Gbps的QAM(正交调幅)信号，使用马赫曾德尔调制器(MZM)以连续波(CW)调制，然后通过单模光纤(SMF)传输，该系统具有很高的数据速率，并且具有成本效益。
