Abstract :
For seamless multimedia streaming services, it is very important to overcome severe ICI (intercell interference) over wireless networks, particularly in the cell border region. SVC (scalable video coding) has been actively studied due to its advantage of channel adaptation. In this paper, we study an optimal solution for maximizing the expected visual entropy over an OFDM (orthogonal frequency division multiplexing)-based broadband network from the aspect of cross layer optimization. Based on this approach, an optimal set of source and channel parameters is obtained according to the user location over a multi-cell environment. From the numerical results, we quantify the optimal visual gain attained from the single layer video coding or the SVC according to channel capacity v.s. source data rate.
