Performance Improvement of RoF & FSO based Hybrid Network using Multi Beam Transmission
Abstract: Radio over Fiber and Free Space Optics has become a popular technology to provide wireless data services to mobile users. But both have their own limitations when implemented separately. In this manuscript, we have proposed a multi beam transmission assisted hybrid network based on Radio over Fiber and Free Space Optics. It is revealed that by deploying multiple beams in the free space transmission, the data rate is enhanced by …

BER Performance Analysis for Digital Modulation Techniques in AWGN Channel of FSO Communication System with Low Attenuation Coefficient
Abstract: BER is a potential methodology for examining digital transmission systems by providing a measurable and useful indication of system performance. If the BER rises within limit then the system performance will be obviously satisfactory. The paper represents BER performance of FSO communication system for a few number of digital modulation techniques: BPSK, QPSK, 4-QAM and 16-QAM in AWGN channel by exploiting the Matlab simulated BER versus SNR graphs. The numerical …

Analysis of FSO Communication System under different weather conditions by incorporating Pre and Post Optical Amplifier
Abstract: AbstractFSO Communication is currently needed for the modern era because of high channel capacity and bandwidth. FSO is a line of sight; license free and low-cost technology which makes it preferred over radio frequency communication and other wireless technologies. In this paper, the first part tells about the introduction of the FSO system, its advantages, disadvantages and applications. The second part will discuss the atmospheric attenuation caused by different weather …
