A Virtual Instrument for Highly Concentrated Time-frequency Distributions
نویسندگان
چکیده
A virtual instrument for highly concentrated time-frequency distributions is proposed in this paper. It provides efficient solutions for the analysis of signals with highly non-stationary instantaneous frequency. The timefrequency distributions of different orders are considered. Thus, due to the variations of signal phase function, the order of the distribution can be increased until a satisfactory concentration is achieved. The instrument could be used for both monocomponent and multicomponent signals. Application of this instrument is demonstrated on the examples.

A virtual instrument for time-frequency analysis
A virtual instrument for time–frequency analysis is presented. Its realization is based on an order recursive approach to the time–frequency signal analysis. Starting from the short time Fourier transform and using the S-method, a distribution having the auto-terms concentrated as high as in the Wigner distribution, without cross-terms, may be obtained. The same relation is used in a recursive ...
متن کاملHighly concentrated time-frequency distributions: pseudo quantum signal representation
Distributions that are highly concentrated in the time-frequency plane are presented. Since the idea for these distributions originated from the Wigner representation in the quantum mechanics, a review of this representation is done in the first part of the paper. Abstracting the physical sense of the quantum mechanics representation, we defined the “pseudo quantum” signal representation. On th...
متن کاملDesigning a new robust control for virtual inertia control in the microgrid with regard to virtual damping
Background and Objectives: Virtual inertia control, as a component of a virtual synchronous generator, is used for the implementation of synchronous generator behaviour in microgrids. In microgrids that include high-capacity distributed generation resources, in addition to virtual inertia, virtual damping can also lead to improvement of frequency stability of the microgrid. The purpose of the c...
متن کاملSparse Time-Frequency Representation for Signals with Fast Varying Instantaneous Frequency
Abstract: Time-frequency distributions have been used to provide high resolution representation in a large number of signal processing applications. However, high resolution and accurate instantaneous frequency (IF) estimation usually depend on the employed distribution and complexity of signal phase function. To ensure an efficient IF tracking for various types of signals, the class of complex...
متن کاملA Class of Highly Concentrated Time-Frequency Distributions Based on the Ambiguity Domain Representation and Complex-Lag Moment
A class of time-frequency distributions with complex-lag argument is proposed. It is based on the ambiguity domain representations of real and complex lag moment, combined to provide a cross-terms free representation for multicomponent signals. Furthermore, the distributions from the proposed class provide a more effective instantaneous frequency estimation for signals with fast varying phase f...
