The quickly developing interest for the remote transmission of video, discourse and data is driving the communication innovation to be more productive and more solid. MIMO has turned out to be one of the key advances for remote communication frameworks. One of the promising transmit diversity plan is Alamouti space time block codes (A-STBC). In this paper, ways to deal with enhance the data rate over the multiple radio wire channels for dependable communication has been implemented. Dissimilar to, the vast majority of the strategy exists to accomplish full assorted qualities and full rate, we expect to build the data rate over the channel by utilizing mark channel display. Furthermore, we studied Alamouti and Silver STBC-MIMO system performance under different mobile radio channel such as dent channel model and Rayleigh channel model. It is clearly observed by the simulation result that the system performance enhances using dent channel model.
