Adaptive resource allocation method over OFDMA system for H.264 SVC transmission

This paper combines adaptive sub-carriers allocation, power allocation in OFDMA with the transmission of the H.264 SVC (Scalable Video Coding) encoded video sequences in order to support more user and provide better quality of service (Qos) to the subscribers. Firstly we compute the maximum number of users the system can support by our proposed CAC (call admission control), and then our proposed adaptive resource allocation algorithm is utilized to allocate resource to these users On the premise of meeting the most basic requirements of all the users, our proposed scheme can select appropriate resolution adaptively for users according to the channel information. Experimental results demonstrate that our scheme performs better than systems with a fixed resource allocation strategy.
