Simulation and estimation for cooperative communication performance in wireless communication systems

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 challenge 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.
