摘要：
In this correspondence, an exact and most revealing expression of the high signal-to-noise (SNR) first-order perturbation variance of the single 2-D 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 1-D 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 1-D specialized version.
