Performance Analysis of Free Space Optical Communication Network with Different Modulation Techniques

Free space optics is one of the emerging technology of optical wireless communication which refers to propagation of light beams through atmosphere for broadband communication. It is a promising alternative solution for RF network, as it provides stable data transmission and highest data rates. However performance of this system could be prominently degraded due to various atmospheric conditions that may lead to increase in bit error rate and affect link sustainability. This paper presents analysis of proposed FSO system with comparative study of different modulation techniques under weak turbulence at 1550 nm wavelength in terms of BER and Q factor so as to mitigate adverse effects and improve efficiency.

Important Announcements

All the authors, conference coordinators, conveners, and guest editors kindly check their articles' originality before submitting them to IJCERT. If any material is found to be duplicate submission or sent to other journals when the content is in the process with IJCERT, fabricated data, cut and paste (plagiarized), at any stage of processing of material, IJCERT is bound to take the following actions.
1. Rejection of the article.
2. The author will be blocked for future communication with IJCERT if duplicate articles are submitted.
3. A letter regarding this will be posted to the Principal/Director of the Institution where the study was conducted.
4. A List of blacklisted authors will be shared among the Chief Editors of other prestigious Journals
We have been screening articles for plagiarism with a world-renowned tool: Turnitin However, it is only rejected if found plagiarized. This more stern action is being taken because of the illegal behavior of a handful of authors who have been involved in ethical misconduct. The Screening and making a decision on such articles costs colossal time and resources for the journal. It directly delays the process of genuine materials.
