无线系统中的节点上运行的电池，使能源消耗必须最小化，同时满足给定的吞吐量和延迟的要求被认为是。在这种情况下，最好的调制策略，以尽量减少所需的总能量消耗发送一个给定的比特数进行了分析。总能耗包括传输能耗和电路能耗。对于未编码的系统，通过优化的传输时间和调制参数，它示出了高达80%的节能是可实现的非优化系统。对于编码系统，它示出的编码的好处随传输距离和底层的调制方案。
Wireless systems where the nodes operate on batteries so that energy consumption must be minimized while satisfying given throughput and delay requirements are considered. In this context, the best modulation strategy to minimize the total energy consumption required to send a given number of bits is analyzed. The total energy consumption includes both the transmission energy and the circuit energy consumption. For uncoded systems, by optimizing the transmission time and the modulation parameters, it is shown that up to 80% energy savings is achievable over nonoptimized systems. For coded systems, it is shown that the benefit of coding varies with the transmission distance and the underlying modulation schemes.
