Robust Time-Frequency Distributions with Complex-Lag Argument

The robust time-frequency distributions with complex-lag argument are proposed. They can provide an accurate estimation of fast varying instantaneous frequency in the presence of noise with heavy-tailed probability density function. The L-estimate form of this distribution is defined and it includes the L-estimate form of Wigner distribution as a special case. A modification for multicomponent ...

Time-frequency distributions with complex argument

—A distribution highly concentrated along the group delay or the instantaneous frequency (IF) is presented. It has been defined by introducing signal with a complex argument in time–frequency (TF) analysis. Realization of a signal with complex argument, using signal with a real argument, is described. The reduced interference realization of the complex argument distribution, in the case of mult...

Fpga Realization of Time-frequency Distribution with Complex-lag Argument

Due to its ability to provide good concentration in the time-frequency plane, the fourth order complex-lag time-frequency distribution has been used for the analysis of signals with highly non-stationary instantaneous frequency. In order to make it available for practical applications, an architecture for realization of this distribution is proposed. The FPGA implementation is provided as well....

Robust time-frequency distributions

Study of the additive Gaussian noise influence on time-frequency (TF) distributions is an important issue [Article 9.1]. However, in many practical applications, especially in communications, signals are disturbed by a kind of impulse noise. These noises are commonly modeled by heavy-tailed (long-tailed) probability density functions (pdfs) [6]. It is well known fact that the conventional TF di...

Hardware Realization of Generalized Time-Frequency Distribution with Complex-Lag Argument

A hardware implementation of the Nth order complex-lag time-frequency distribution is proposed. The considered distribution provides an arbitrary high concentration for multicomponent signals with fast varying instantaneous frequency. Although the distribution form is quite complex, the proposed realization is very efficient and provides high-speed real-time processing. Further, it allows avoid...
