Abstract

Efficient transmission of multimedia signals from energy limited portable devices requires a fresh look at the tradeoffs between source compression, channel coding and transmission strategies. We provide optimum operating points in terms of end-to-end source distortion and total energy consumption of the mobile due to compression, channel coding and transmission. We illustrate that the optimum strategy depends on the location of the mobile and that optimizing can prolong the battery life about ten times
