2-D unitary matrix pencil method for efficient direction of arrival estimation

2-D Unitary ESPRIT-Like Direction-of-Arrival (DOA) Estimation for Coherent Signals with a Uniform Rectangular Array

A unitary transformation-based algorithm is proposed for two-dimensional (2-D) direction-of-arrival (DOA) estimation of coherent signals. The problem is solved by reorganizing the covariance matrix into a block Hankel one for decorrelation first and then reconstructing a new matrix to facilitate the unitary transformation. By multiplying unitary matrices, eigenvalue decomposition and singular v...

Unitary Matrix Pencil Algorithm for Range-Based 3D Localization of Wireless Sensor Network Nodes

Most node localization algorithms for wireless sensor network (WSN) are only applicable to twodimensional networks. However, in most cases, nodes are placed in three-dimensional (3D) terrains, such as forests, oceans, etc. In this paper, a range-based 3D localization method is put forward based on time-of-arrival (TOA) estimation of ultra wideband signal using unitary matrix pencil (UMP) algori...

Joint Azimuth and Elevation Angle Estimation Using Incomplete Data Generated by a Faculty Antenna Array

In this study, we extend the "Fault Tolerant Matrix Pencil Method for Direction of Arrival Estimation (DOA)" proposed by the authors [1] to joint estimation of Azimuth and Elevation Angles from a data generated by Uniform Planar Antenna array (UPA), where at random locations a few of the elements due to failure are missing. Joint Azimuth and Elevation Angles estimation is generally known as Two...
