Abstract
The purpose of this paper is to investigate the
nonasymptotic behavior of the maximum likelihood method in
the context of lacunar array processing. We derive an analytical
expression of the maximum likelihood mean square error, which is
now valid for all signal-to-noise ratio (SNR) ranges. We also provide
an analysis of the SNR threshold phenomena, which allows us
to derive closed-form formulas for the threshold values. Computer
simulations confirm the validity of the theoretical investigations.
