A Sparse Representation Method for Coherent Sources Angle Estimation with Uniform Circular Array

Cuba-esprit for Angle Estimation with Circular Uniform Beam Arrays

Currently, spatial signal processing for adaptive source separation and interference cancellation are extensively discussed for application in future mobile radio systems. ESPRIT-type algorithms are especially concerned because of their low arithmetic complexity and their inherent ability for superresolution estimation of the direction of arrival (DoA) [1]. The latter is also true for mobile ra...

Frequency and 2D Angle Estimation Based on a Sparse Uniform Array of Electromagnetic Vector Sensors

We present an ESPRIT-based algorithm that yields extended-aperture two-dimensional (2D) arrival angle and carrier frequency estimates with a sparse uniform array of electromagnetic vector sensors. The ESPRIT-based frequency estimates are first achieved by using the temporal invariance structure out of the two time-delayed sets of data collected from vector sensor array. Each incident source’s c...

A New IRIS Segmentation Method Based on Sparse Representation

Iris recognition is one of the most reliable methods for identification. In general, itconsists of image acquisition, iris segmentation, feature extraction and matching. Among them, iris segmentation has an important role on the performance of any iris recognition system. Eyes nonlinear movement, occlusion, and specular reflection are main challenges for any iris segmentation method. In thi...
