A new pseudo-noise resampling technique is proposed to mitigate the effect
of outliers in Unitary ESPRIT. Our algorithm improves the performance of Un
itary ESPRIT in unreliable situations, where the so-called reliability test
has a failure. For this purpose, we exploit a pseudo-noise resampling of a
failed Unitary ESPRIT estimator with a censored selection of "successful"
resamplings recovering the nonfailed outputs of the reliability test.
