System Identification Based on Frequency Response Noisy Data
In this paper, a new algorithm for system identification based on frequency response is presented. In this method, given a set of magnitudes and phases of the system transfer function in a set of discrete frequencies, a system of linear equations is derived which has a unique and exact solution for the coefficients of the transfer function provided that the data is noise-free and the degrees of...

متن کاملFrequency Domain Fractional Delay Estimation for Noisy Channels
A channel delay can be estimated by evaluating the channel response to a deterministic signal. In the frequency domain, a maximum likelihood delay estimator which accounts for colored Gaussian measurement noise can be formulated. A procedure that allows fast estimation of the channel delay is proposed, in case a low-pass deterministic signal is applied to the channel. Keywords—Fractional delay;...
متن کاملTime-frequency Models with Noisy Partials
STUB. 1 Time-frequency Models Useful manipulations of sound signals—such as time stretching, pitch shifting, and timbral interpolation—depend on time-frequency models of a sound consisting of amplitudeand frequency-modulated sinusoidal partials. We use the exponential presentation of a complex-valued signal ψ:
متن کاملHigh Dimensional Structured Estimation with Noisy Designs
Structured estimation methods, such as LASSO, have received considerable attention in recent years and substantial progress has been made in extending such methods to general norms and non-Gaussian design matrices. In real world problems, however, covariates are usually corrupted with noise and there have been efforts to generalize structured estimation method for noisy covariate setting. In th...
