Abstract:
This aim of this work is to propose a massive MIMO FSO system with optimum
design parameters and analyze its performance in various turbulent weather
conditions by simulating the model in Optisystem . In recent years, the need
for high speed data transfer for real time communication has become a
necessity. Implementation of massive MIMO system has already gained
remarkable achievement using the conventional RF transmission system.
Although it is very much efficient in its application, it has some problems, such
as licensing restrictions, bandwidth depletion, fragmentation. In this respect,
Free space optics (FSO) is an efficient method for high speed data transfer as it
does not have above limitations. Different researches conducted using MIMO
FSO models have shown promising results. The use of massive MIMO system
(more than array of antennas) will enhance data rate further. In this
research work, an optimum massive MIMO FSO system has been designed with
array of antennas. The performance of this system is analyzed in
different weather conditions and compared with that of system. The
analysis of performance is done by power penalty and receiver sensitivity plots.
A significant transmission range and an optimum performance is obtained by
using this system at a data rate of Gbps. However, data transmission rate can
be much more enhanced in this system at the cost of reduced performance and a
shorter transmission range.
