Abstract: Multiple Input and Multiple Output (MIMO) and Orthogonal Frequency Division Multiplexing (OFDM) system have the potential to achieve a very high capacity relaying on the propagation environment. The main objective of this paper is to allocate resources on MOBILE-CRN using the adaptive resources allocation in MIMOOFDM system by using the water filling algorithm. Water filling solution is implemented to allocate power in order to decrease channel capacity for power consumption. A MOBILE -CRN-Advanced cooperative cellular network where a Type II relay station (RS) is deployed to boost the cell-edge throughput and extend the coverage area. To better exploit the existing resources, the RS and eNodeB (eNB) transmits in same channel (In-Band) with decode-and-forward relaying strategy. For such a type of network, in this paper we propose a joint Orthogonal Frequency Division Multiplexing (OFDM) subcarrier and power allocation schemes to optimize downlink multi-user transmission efficiency.
