About the Project
In this project, the aim and objectives are to simulate, design and optimise the performance of RoFSO system for next generation 5G-LTE systems. Single carrier modulation schemes such as quadrature amplitude modulation (QAM) and OOK-NRZ are normally used in RoFSO systems due to its simplicity. However, to increase the capacity and speed for 5G mobile communication system, in this project, multicarrier modulation schemes such as orthogonal frequency division multiplexing (OFDM) will also be implemented.
The dynamic growth of mobile users is one of the most important motivations that have led to 4th generation- long term evolution (4G-LTE) and currently the global race for the development of fifth generation (5G) mobile networks. In 4G-LTE mobile communication, currently, the base station are connected with radio or microwaves frequency bands, which are already congested and hence the speed of 4G-LTE mobile systems is already slowed dramatically since they were launched three years ago . To enhance the mobile internet speed to the end users in urban areas. Modern and expensive fibre optics based infrastructure is required to connect the mobile base stations using radio over fibre links.
However, to lay down the fibre in busy urban streets particularly in city centres is not easy as it requires to trench roads and hence this can create huge disruptions and thus impact on the economic, environment and social life of busy urban areas. Therefore, in this project a radio over free space optics (RoFSO) system will be proposed. RoFSO is a low cost, energy efficient, high bandwidth, free space optics (FSO) based system that is capable of providing high speed communication links (100 Gb/s) to connect mobile base stations without the need of fibre cables and trenching the roads [1].
FSO uses optical spectrum (via lasers or LEDs) to transmit high speed data (100 Gb/s) wirelessly through atmosphere up to 5 km. Some of the applications of FSO are to provide high-speed broadband internet to commercial/residential buildings to buildings, campuses to campuses, and hospitals to hospitals, mobile base station to base stations to name but a few. However, the performance of RoFSO is highly dependent on outdoor atmospheric conditions, such as aerosols, fog and turbulence that degrade the laser light signals [2].
In this project, the aim and objectives are to simulate, design and optimise the performance of RoFSO system for next generation 5G-LTE systems.
