Query: New Methods for MLE of Toeplitz Structured Covariance Matrices with
  Applications to RADAR Problems   This work considers Maximum Likelihood Estimation (MLE) of a Toeplitz
structured covariance matrix. In this regard, an equivalent reformulation of
the MLE problem is introduced and two iterative algorithms are proposed for the
optimization of the equivalent problem. Both the strategies are based on the
Majorization Minimization (MM) framework and hence enjoy nice properties such
as monotonicity and ensured convergence to a stationary point of the equivalent
MLE problem. The proposed algorithms are also extended to deal with MLE of
other related covariance structures, namely, the banded Toeplitz,
Toeplitz-block-Toeplitz, low rank Toeplitz structure plus a scalar matrix
(accounting for white noise), and finally Toeplitz matrices satisfying a
condition number constraint. Through numerical simulations, it is shown that
new methods provide satisfactory performance levels in terms of both mean
square estimation error and signal-to-interference-plus-noise ratio.
