Abstract: In this paper, an active single‐object localization system with U‐shaped ultrasonic module array is presented. The proposed algorithm in this system has two stages. The first stage is time‐of‐flight (TOF) estimation of reflected ultrasonic signals.… read more here.

Abstract: This letter presents a novel approach to blind recovery of audio signals that have been distorted by a memoryless, invertible, and smooth nonlinear function. We introduce a cost function consisting of a weighted sum of… read more here.

DOI: 10.1109/tsp.2017.2703667
Abstract: This paper investigates the constrained weighted least squares (CWLS) source localization problem by using time difference of arrival and frequency difference of arrival measurements. The problem can be formulated as a quadratic programming with two… read more here.
