Abstract

All-optical Orthogonal Frequency Division Multiplexing (OFDM) evokes a new regime in advanced optical communication at extreme data rates, as subcarriers are multiplexed and demultiplexed using trigonometric transforms. This paper shows that real trigonometric transforms can advantageously replace the Fourier Transform in optical communication systems, for all-optical signal processing. A low-complex, real trigonometric transform-based Orthogonal Frequency Division Multiplexing for Radio-over-Fiber system (RoF) is presented. The modulation/demodulation is performed by using the Fast Hartley Transform (FHT). The system is modeled and simulated using latest commercial software, Optisystem. This is an exquisite method that uses standard components of optical telecommunication. As a result this model can be used with different wireless communication systems such as high date rate Wireless LANs, Fiber-To-Home (FTTH), Wi-Max and the 4th generation cellular systems. It also find applications in inter connecting nano-photonic systems remotely over wireless systems.

一种用于光纤无线通信系统的低复杂度实光子OFDM

全光正交频分复用(OFDM)在极端数据速率下引发了先进光通信的新体制，因为子载波使用三角变换进行多路复用和解路复用。在光通信系统中，实三角变换可以很好地取代傅立叶变换，用于全光信号的处理。提出了一种低复杂度、基于实三角变换的光纤无线电系统(RoF)正交频分复用技术。调制/解调是通过使用快速哈特利变换(FHT)进行的。该系统采用最新的商业软件Optisystem进行建模和仿真。这是一种利用光通信标准元件的精巧方法。因此，该模型可用于不同的无线通信系统，如高数据速率无线局域网，光纤到户(FTTH)， Wi-Max和第四代蜂窝系统。它也发现了应用在通过无线系统远程连接纳米光子系统。
