Abstract

An exact and most revealing expression of the high signal-to-noise (SNR) first-order perturbation variance of the single 2D frequency estimate using the matrix enhancement and matrix pencil (MEMP) method is provided. This expression is a general form consistent with several previously reported expressions for the 1D frequency case. Based on this expression, the statistical efficiency of the MEMP method is discussed. The optimum efficiency of the MEMP method is shown to be achieved by its 1D specialized version
