In this paper, multi-hop cooperative relaying system will be studied. Multi-antennas system will be applied at multi hopping relay nodes to improve Signal to Noise Ratio (SNR) of the transmitted signal at its destination which is not clarified until now. The performance of the system will be compared with using single antenna at relay nodes under different kinds of modulations. Analysis of the system will be made. Fixed power amplifies and forward strategy will be used at relay nodes.
