Subcarrier Analysis and Power Allocation for Cooperative Communication in LTE ?Advanced Networks

Mohammed Abdul Rahman, Naziaparveen

The long term evolution (LTE-Advanced) is a standard introduced by 3rd Generation Partnership Project (3GPP). LTE-Advanced provides many benefits like high-speed data, bandwidth efficiency, latency, multimedia unicast and multimedia broadcast services to cellular networks. In cellular LTE-Advanced network as Base station or Enb (evolved nodeb) needs to perform resource allocation in changing environment, efficient joint resource allocation schemes for throughput maximization with low computational cost are preferred. Since the throughput maximization problem is mixed integer nonlinear problem (MINLP) optimal joint resource allocation scheme is implemented to solve this problem.. By implementing optimal joint resource allocation scheme higher achievable rate can be obtained when relay station operates in synchronous case than in asynchronous. However, synchronous case leads to high coding complexity that will increase the implementation cost significantly. So for further enhancement of overall throughput is done when relay station operates in asynchronous mode by the use of multiple relays and proposed gradient power allocation method and is compared with optimal resource allocation scheme
