tfd meaning in Chinese
函数依赖
Examples
- To cancel the wideband nonstationary interference , the interference suppression technology based on the time - frequency distribution ( tfd ) property is proposed
针对宽带非平稳信号,基于时频分析的干扰抑制算法是一项非常有效的措施。 - When the echoes have multi - components there are much cross - components in the time - frequency distribution ( tfd ) , so it is not suitable for the feature extraction of the echoes
当回波信号为多分量信号时，时频分布中含有大量的交叉项。交叉项的存在，一方面对信号处理的结果产生干扰，不利于回波信号的特征提取。 - Cross - components suppression is always the intractability in the studies of tfd and the difficulty in signal processing we should overcome . on the other hand , the cross - components have much information of two ( or more ) signal components , so it is suitable for signal detection
因此，抑制交叉项一直是时频分析研究领域一个十分棘手的问题，同时也是时频分析得以更广泛应用于各信号处理领域所要克服的网难之一。 - At the same time , the coordinate representation also can be exploited in calculating thermal non - classical states recently , such as coherent state . basing on the correlative theory , and within the framework tfd , we calculate rindler oscillator ' s information - entropy in the coordinate representation , and discuss the relation of its general uncertainty relationship and information - entropy , especially the relation of its thermal fluctuation and information - entropy
在相关理论的基础上，本文一方面利用热场动力学，在坐标表象下计算出了与一维rindler谐振子的位子和动量有关的信息熵，并给出了信息熵与一维rindler谐振子的广义测不准关系，特别是与热扰动之间的联系。
