Abstract:
Explosively increasing demands for the wireless multimedia data have accelerated to research for adapting higher quality video applications in extensive efforts. In this paper, we explore a theoretical approach to cross-layer optimization between multimedia and wireless network by means of a quality criterion termed "visual entropy" for downlink video transmission, using a layered coding algorithm. We obtain the optimal loading ratio through an optimization problem, which aims at balancing the trade-off relationship between ICI (Inter-Cell Interference) and channel throughput. In the simulation, we show that the throughput gain in terms of visual entropy at the cell boundary is increased by up to about 32%.
