Tone and Chirp Detection Using Sums of Conjugate Products
نویسنده
چکیده
We analyse a class of simple statistics, which we call sums of conjugate products, for the purpose of detecting tones and chirps in noise. These statistics have been studied before for their powers of estimation. In this paper, we derive their asymptotic statistics and compare their discriminating power against the energy detector. We find that a modest improvement over the energy detector is achieved for tone detection, but that the energy detector has superior performance in the case of chirps. Numerical results are presented, which are found to be in good agreement with the theoretical predictions.

Crack Detection In Functionally Graded Beams Using Conjugate Gradient Method
In this paper the conjugate gradient (CG) method is employed for identifying the parameters of crack in a functionally graded beam from natural frequency measurement. The crack is modeled as a massless rotational spring with sectional flexibility. By using the Euler-Bernoulli beam theory on two separate beams respectively and applying the compatibility requirements of the crack, the characteris...

متن کاملChirp Excitation of Ultrasonic Guided Waves (preprint)
Most ultrasonic guided wave methods require tone burst excitations to achieve some degree of mode purity. In addition, it is often desirable to acquire data using multiple frequencies, particularly during method development when the best frequency for a specific application is not known. However, this process is inconvenient and time-consuming, particularly if extensive signal averaging at each...

Abstract: In this paper, we exhibit new conditions for the sum of two commuting AC-operators to be again an AC-operator. In particular, this is satisfied on Hilbert space when one of them is a scalar-type spectral operator.
متن کاملRobust Timing Offset Estimation Using Sub-autocorrelation Functions for Uni- and Bi-directional Chirp Signals
In this paper, we present a robust timing offset estimation method using subautocorrelation functions for uniand bi-directional chirp signals. The presented timing offset estimator is designed to be applied with a generalized chirp signal sequence, which use unior bi-directional chirp symbols. Using the conjugate property of the chirp signal, the sub-autocorrelation functions are generated to b...
