ESPRIT算法估计性能分析

摘要

波达方向估计(DOA)技术渐渐成为移动通信中研究的热点,而ESPRIT算法是一种典型算法.在对ESPRIT算法进行分析的基础上,介绍了几种ESPRIT算法,并从信噪比、阵元数等不同情况下对几种算法的性能进行了仿真分析.%Direction of Arrival( DOA) estimate has become of the key issues in mobile communications,and ESPRIT is a typical algorithm. This paper designs a MATLAB simulation on the analysis of ESPRIT algorithm and studies several ESPRIT algorithms. It makes comparisons and analyses among different algorithms from the angles of signal and noise ratio( SNR) and the number of array.
