Abstract
With the rapid increasing demands of wireless media applications, it becomes more and more important on video transmission technologies. With the rapid growth of media application, QoE (quality of experience), that is the standard of quality of service, many researchers focus on the topic of the application of QoE in wireless communications. This paper presents an energy effective QoE-aware resource allocation algorithm in multiuser Multiple Input Multiple Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) systems. The resource allocation problem is formulated to maximize the overall QoE by jointly considering the subcarrier allocation under the total power constraint. We have analyzed the performance of wireless communication according to both RD (rate distortion) in the upper layer and the channel condition in the PHY layer (physical layer). In the simulation results, we can see that the proposed resource allocation algorithm has maximized the quality of video under the minimum of the sum distortion of all video streaming with the time-varying wireless channels under total constraints of power.
