摘要

自由空间光通信(FSO)通过允许光穿过大气提供高数据速率。它是一种非常有效的无线通信技术。这一新兴领域主要使用不可见的光束，如紫外线、红外线等。本文专门研究了利用Opti-System 7.0仿真软件，采用最小移键控和差相移键控，设计基于波分复用的FSO系统。他们进一步研究了哪种调制技术能提供更好的通信手段。正常雨量的减弱是根据六个月的雨量资料来评估的。在使用雨衰减20.5dBm时，根据误码率、q因子和接收器灵敏度对未来系统的一致性进行了评估。传输波长和数据速率分别为1550nm和2.5Gbps。

Impact of Modulation Techniques for Hybrid-WDM Based FSO

Free space optical communication (FSO) provides high data rate by allowing light passed through the atmosphere. It is very effective and efficient technology for wireless communication. This emerging field basically uses invisible beams of light such as ultraviolet, infrared, etc. This work exclusively deals with the designing of hybrid WDM based FSO system using the simulation software Opti-System 7.0 with Minimum-Shift Keying and Differential-phase-shift keying. Further their study has been made as to which modulation techniques provides better means of communication. The normal rain weakening is assessed from rain power information which are gathered for a period for six months. The concert of the future system is evaluated in terms of Bit Error Rate, Q-factor, and Receiver Sensitivity are examined with respect to link distance for using rain attenuation 20.5dBm. The transmission wavelength and data rate is 1550nm and 2.5Gbps considered for investigation.
