Construction of positive time-frequency distributions

چکیده
AbstructA general method for constructing nonnegativedefinite, joint time-frequency distributions (TFD’s) satisfying the marginals of time Is(t)l ’ and frequency lS(f)12 is presented. As nonnegative-definite distributions with the correct marginals, these TFD’s are members of the Cohen-Posch class. Several examples illustrating properties of these TFD’s are presented for both synthetic and real signals.

The online observation of a construction site and processes bears significant advantage to all business sector. BIM is the combination of a 3D model of the project and a project-planning program which improves the project planning model by up to 6D (Adding Time, Cost and Material Information dimensions to the model). RFID technology is an appropriate information synchronization tool between the...
متن کاملJoint Distributions of Arbitrary Variables Made Easy
In this paper, we propose a simple framework for studying certain distributions of variables beyond time-frequency and time-scale. When applicable, our results turn the theory of joint distributions of arbitrary variables into an easy exercise of coordinate transformation. While straightforward, the method can generate many distributions previously attainable only by the general construction of...
متن کاملLinear and quadratic methods for positive time-frequency distributions
This paper presents a new foundation for positive time{ frequency distributions (TFDs). Based on an integral equation formulation of nonstationary systems, a positive TFD can be constructed from a decomposition of a signal over an orthonormal basis. This basis function de nition of a positive TFD is used to obtain a relationship between the Wigner distribution and the positive TFD. The results ...
متن کاملLow flow frequency analysis by L-moments method (Case study: Iranian Central Plateau River Basin)
Knowledge about low flow statistics is essential for effective water resource planning and management in ungauged orpoorly gauged catchment areas, especially in arid and semi-arid regions such as Iran. We employed a data set of 20 riverflow time-series from the Iranian Central Plateau River Basin, Iran to evaluate the low-flow series using several frequencyanalysis methods and compared the resu...
