In this paper, the optimal channel capacity of cooperative system with or without channel state information (CSI) has been analyzed by simultaneously taking both relay location and power allocation into consideration. The proposed model is a dual-hop relay system with signal from a source to a destination through the relay using the decode-and-forward (DF) strategy. The numerical results show that the optimal channel capacity of system with CSI is significantly better than the one without CSI.
