论文摘要
实现失真噪声曲线所需的最小功率，即，研究了指示每个噪声水平的最大允许失真值的函数，研究了高斯源在带宽范围内的高斯通道上传输高斯通道的传输。提出了一个简单但有工具的下限，即给定轮廓的最小功率。对于上限，提出了基于肮脏的编码方案，并分析了其功率差异。最后，分析了最小功率的上限和下限，并比较了特定的失真噪声曲线，即具有一和第二顺序的理性曲线。
Minimum power required to achieve a distortion-noise profile, i.e., a function indicating the maximum allowed distortion value for each noise level, is studied for the transmission of Gaussian sources over Gaussian channels under a regime of bandwidth approaching zero. A simple but instrumental lower bound to the minimum required power for a given profile is presented. For an upper bound, a dirty-paper based coding scheme is proposed and its power-distortion tradeoff is analyzed. Finally, upper and lower bounds to the minimum power is analyzed and compared for specific distortion-noise profiles, namely rational profiles with order one and two.
