A signal reconstruction theorem under complete set of orthogonal integral transform 完备正交积分变换下的信号重构
The reconstruction project of shanghai metro line 1 is carried cut in accordance with the master plan of the south station , construction subsequence , signal reconstruction plan and vehicle operation organization 摘要介绍了上海轨道交通1号线上海南站站改建工程的总体设计方案、施工拨接计划、施工顺序、信号改造过渡方案、列车运行组织以及施工拨接的全过程。
The ridge characteristic related closely to the instantaneous frequency of the signal . a serial of ridge extraction and signal reconstruction algorithms have been developed using phase or module information of parameters on the ridges 由此发展出一系列根据变换域参数的相位信息、模值信息等提取脊的方法,同时也发展出各种利用脊上的信息对信号进行重建的方法。
Some of the signal characteristics can be better presented in certain transformed domain , so that in order to describe such features , it being necessary to study the character extraction and signal reconstruction algorithms based on information from transformed domain 信号的某些特征在变换域上能够得到更好的表示。为了进行信号特征的提取,需要将采样得到的时域信号在相应的变换域上表示出来,从而得到对信号特征更好的描述并进行提取。
