this research studies 2x2 MIMO LTE signal transmission from the
main tower eNB and the relay node RN over single mode fiber
using ROF technology and take advantage of the WDM technology,
the results show the ability of ROF to accommodate MIMO
com
munication with high efficiency.
The network has been simulated and analyzed using Optisystem
program, and the results were more than promising.
Although Multi-Input-Multi-Output MIMO improve reliability of wireless
transmission system and increase bit rate, but this improvement relay on higher cost in
Hardware and increase in size as well as complex structure, so the cost-effective challen
ge
still exists to implement these technique.
Performance can be improved without increasing the cost significantly by using
virtual MIMO systems where the spacing is achieved by using pre-existing devices within
the network infrastructure, these systems called cooperative communication systems,
which are the subject of this research.
The simulation is based on standard software for modeling MATLAB and open
sourced Network simulator-3 (NS-3) to characterize problems in wireless communications
systems and propose appropriate solutions.
