The expectation–maximization (EM) algorithm is often used in maximum likelihood (ML) estimation problems with missing data. However, EM can be rather slow to converge. In this communication we introduce a new algorithm for parameter estimation problems with missing data, which we call equalization–maximization (EqM) (for reasons to be explained later). We derive the EqM algorithm in a general context...
In this correspondence, a new time reversal (TR) based ultra-wideband (UWB) microwave method for hyperthermia treatment of breast cancer is presented. Two high-resolution techniques, time reversal (TR) and robust Capon beamformer (RGB), are employed to shape the transmitted signals both temporally and spatially. As shown in the two-dimensional (2D) numerical simulations, this method has better electromagnetic...
We propose a new multi-static adaptive microwave imaging (MAMI) method for early breast cancer detection. MAMI is a two-stage robust Capon beamforming (RCB) based image formation algorithm. MAMI exhibits higher resolution, lower sidelobes, and better noise and interference rejection capabilities than the existing approaches. The effectiveness of using MAMI for breast cancer detection is demonstrated...
