Abstract

Multiple Input and Multiple Output (MIMO) and Orthogonal Frequency Division Multiplexing (OFDM) system have the potential to attain very high capability depends upon the propagation surroundings. the target of this paper resource allocation on LTE exploitation is that the reconciling resource allocation in MIMO-OFDM system exploitation the water filling formula. Water filling resolution is enforced for allocating the ability so as to decrease the data rate for power consumption. A LTE-Advanced cooperative cellular network wherever a sort II relay station (RS) is deployed to reinforce the cell-edge turnout and to increase the coverage space. to higher exploit the present resources, the RS and also the eNodeB (eNB) transmit within the same channel (In-Band) with decode-and-forward relaying strategy. For such a network, this paper proposes joint Orthogonal Frequency Division Multiplexing (OFDM) subcarrier and power allocation schemes to optimize the downlink multi-user transmission the aim.

Keywords: Synchronous and Asynchronous Mode, LTE etc.
