Bayesian information criterion for multidimensional sinusoidal order selection

Jie Xiong, Kefei Liu, João Paulo Carvalho Lustosa da Costa, Wen-Qin Wang

ICASSP 2017accepted

Detecting the sinusoidal order is a prerequisite step for parametric multidimensional sinusoidal frequency estimation methods, whose applications range from radar and wireless communications to nuclear magnetic resonance spectroscopy. Although the Bayesian information criterion (BIC) has been common…

Unscented Transformation based array interpolation

Marco A. M. Marinho, João Paulo Carvalho Lustosa da Costa, Felix Antreich, Leonardo R. A. X. de Menezes

ICASSP 2015accepted

It is impossible to enforce exact responses for each sensor involved in an antenna array. Important signal processing techniques such as Estimation of Signal Parameters via Rotational Invariance (ESPRIT), Forward Backward Average (FBA) and Spatial Smoothing (SPS) rely on sensor arrays with Vandermon…
