从能量有限的便携式设备的多媒体信号的有效传输需要在源压缩，信道编码和传输策略之间的权衡新的眼光。我们提供了最佳的工作点在端到端的源失真和总能耗的移动的由于压缩，信道编码和传输。我们说明了最佳策略取决于移动的的位置，优化可以延长电池寿命约十倍。
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.
