Abstract:

We consider the real time transmission of scalable multimedia data with a constrained end-to-end Quality of Service. In the Rayleigh channel case, the resulting optimization problem is solved by the Flexible Transmission (FT) algorithm. This resources allocation strategy allows to transmit the sole layers with guaranteed QoS at the receiver. Here, we propose to extend the FT method to the OFDM case. The resulting algorithm is incorporated into a multimedia application using MPEG-4 speech frames, in order to compare the performance of our approach with those of other unequal error protection schemes. Simulation results show the efficiency of our solution and its adaptivity to frequency channel selectivity.
