The feasibility of sparse signal reconstruction depends heavily on the inter-atom interference of redundant dictionary. In this paper, a semi-blindly weighted minimum variance distortionless response (SBWMVDR) is proposed to mitigate the inter-atom interference. Examples of direction of arrival estimation are presented to show that the orthogonal match(More)
PURPOSE Glaucoma is an eye disease that can lead to irreversible optic nerve damage and cause blindness. Optical coherence tomography (OCT) allows an early diagnosis of glaucoma by the measurements of the retinal nerve fiber and optic disc parameters. A retrospective study was designed to analyze the effects of the measurement of the retinal nerve fiber(More)
PURPOSE To investigate the influence of phacoemulsification on corneal endothelial cells in diabetes patients and normal controls. METHODS Phacoemulsification and intraocular lens implantation were performed on 75 patients with diabetic cataract (126 eyes) who were divided into two groups: Experimental group 1 (Glu ≤ 6mmol/L); Experimental group 2 (Glu(More)
PURPOSE To investigate the genotyping of Foxp3-3279 (A/Crs376158) genes in patients with dust mite-induced allergic conjunctivitis from Guangdong province and to explore the association between these genes and the susceptibility to dust mite allergic conjunctivitis. METHODS In total, 80 patients with dust mite allergic conjunctivitis and 103 healthy Han(More)
This paper exploits recent developments in sparse approximation and compressed sensing to efficiently perform the direction finding. The new method is proposed based on unimodal characteristic of antenna pattern and sparse property of received data. Unlike the conventional methods based peak-searching and symmetric constraint, the sparse reconstruction(More)
