Asymptotic robustness of sensor array processing methods
Björn Ottersten, Mats Viberg · International Conference on Acoustics, Speech, and Signal Processing · 2002
Methods for estimating the parameters of narrowband signals arriving at an array of sensors are analyzed. Asymptotic results for several estimators have recently appeared in the literature. With few exceptions, the previous analysis requires the incident signal waveforms to be Gaussian random variables. These results are shown to be valid under much more general conditions, i.e. the actual distribution of the signal waveforms does not affect the asymptotic properties of the parameter.>
