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 ...
Abstract: This paper presents a coupler with programmable phase-difference characteristic implementable for Butler Matrix applications. To achieve the characteristics, capacitors are placed at each ...
