Abstract

In this work, the performance of wavelength division multiplexing based radio over free space optics (WDM-RoFSO) communication system is investigated utilizing OptiSystem 0.7 software. Four weather conditions are adopted in this paper, namely, clear, haze, rain and fog with attenuation losses of 0.2 dB/km, 2.3 dB/km, 4.3 dB/km and 8 dB/km, respectively In addition, a high radio frequency of 30 GHz with high bit rate of 160 Gbps is modulated and carried on optical signal for fifth generation (5G) applications. The dual channel technique is employed in order to enhance the performance parameters of proposed WDM-RoFSO communication system. The enhancement in the link range is about; 46.1%, 35%, 29.4% and 25.9% for clear, haze, rain and fog, respectively.

摘要

在这项工作中，利用OptiSystem 0.7软件研究了基于波分复用的自由空间光无线通信（WDM-RoFSO）系统的性能。本文采用了四种天气条件，即晴天、薄雾、雨天和雾天，其衰减损耗分别为0.2 dB/km、2.3 dB/km、4.3 dB/km和8 dB/km。此外，为了用于第五代（5G）应用，将30 GHz的高频和160 Gbps的高比特率调制并承载在光信号上。采用双通道技术以提高所提出的WDM-RoFSO通信系统的性能参数。对于晴天、薄雾、雨天和雾天，链路范围的增强分别约为46.1%、35%、29.4%和25.9%。
