In this research, we simulate the wave propagation in surface duct by using the split step Fourier method to solve the parabolic wave equation. The relation between the path loss and the channel parameters as frequency, duct strength and duct height is studied
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.
