A bootstrap scheme for time-frequency auto-term selection in antenna arrays
L.A. Cirillo, Abdelhak M. Zoubir · 2004
A method for detection of source signal auto-term regions in the time-frequency plane, based on spatial time-frequency distribution matrices is presented. As opposed to previous methods, a multiple hypothesis test is used in order to control the family wise error rate strongly when testing multiple locations on the time-frequency plane simultaneously. A bootstrap based method for estimating the distribution of the test statistic is also proposed, and the performance in terms of operating characteristics is compared to that of using an asymptotic distribution.
