Performance Analysis of the 2D-Unitary ESPRIT Algorithm for 5G mmWave Networks

This paper analyzes the 2d-unitary ESPRIT algorithm and investigates its feasibility in 5G networks. The content of this paper can be divided into three parts. In the first two parts of the paper, the mathematical model of the direction of arrival (DoA) algorithm is given. The third part of the paper describes the simulation results of beamforming scenarios considering DoA location in 5G mmWave ultra-dense networks (UDNs). The contribution of this study is the investigation of the dependence of the resolution threshold and accuracy of the 2d unitary ESPRIT algorithm on the number of elements in the antenna array and the value of SINR.
