Robust Parameter Estimation of Contaminated Damped Exponentials

Youye Xie, Dehong Liu, Hassan Mansour, Petros T. Boufounos

ICASSP 2020accepted

Parameter estimation of damped exponential signals has wide applications including fault detection and system parameter identification, etc. However, existing methods for estimating parameters of damped exponentials are either sensitive to noise or restricted to dealing with a certain type of noise…

Sparse Recovery and Non-stationary Blind Demodulation

Youye Xie, Michael B. Wakin, Gongguo Tang

ICASSP 2019accepted

In this paper, we consider a general sparse recovery and blind demodulation model. Different from the ones in the literature, in our general model, each dictionary atom undergoes a distinct modulation process; we refer to this as non-stationary modulation. We also assume that the modulation matrices…
