Abstract :
Adaptive image coding scheme are well adapted to multirate cognitive networks. A Cognitive device will be able to reconfigure itself to adapt its baseband radio transmitter to the required bit rate of the coding scheme. In this paper, a such platform able to adapt the radio access technology (RAT) to the image coding scheme is described. To optimize the RAT bit rate to the image coding bit rate, our system chooses and reconfigures in real time the radio baseband functions. It makes some cross-layer adaptation between PHY and application layers.
