Abstract: A novel two-step iterative optimization method could be used in microwave and mm-wave bands for optimal topology of 2-D sparse multiple-input multiple-output (MIMO) arrays, and an improved ...
Abstract: In this paper, we propose two new algorithms for maximum-likelihood estimation (MLE) of high dimensional sparse covariance matrices. Unlike most of the state-of-the-art methods, which either ...
