Abstract
Previous work has demonstrated that a signal receiver based on a limiting form of the Shannon entropy is, in certain settings, more sensitive to subtle changes in scattering architecture than conventional energy-based signal receivers [M. S. Hughes et al., J. Acoust. Soc. Am. 121, 3542-3557 (2007)]. In this paper new results are presented demonstrating further improvements in sensitivity using a signal receiver based on the Renyi entropy.
摘要
先前的研究表明，在某些情况下，基于香农熵极限形式的信号接收器比传统的基于能量的信号接收器对散射结构的细微变化更敏感[M. S. 休斯等人，《美国声学学会杂志》121, 3542 - 3557 (2007)]。本文展示了新的结果，表明使用基于雷尼熵的信号接收器可进一步提高灵敏度。
