摘要：
A new source coded modulation algorithm optimizing the energy efficiency in information transmission is presented. Wireless communication devices transmit nonuniform-probability messages using nonuniform-energy signal sequences. Hence, energy-optimal information transmission can be achieved by representing higher-probability messages by lower-energy signal sequences. In this paper, first this source coded modulation problem is formulated and an optimization algorithm for designing energy-optimal modulation systems is proposed. Then, a new sub-optimal source coded modulation algorithm achieving energy efficient information transmission at a reduced system complexity is introduced. Finally, extensions of this algorithm are investigated for improving energy efficiency.
