Implementation of Signal Parameters Estimation via Rotational Invariance Technique by Using Graphic User Interface


This paper presents a novel method based on Graphic User Interface (GUI) for estimating the directions of source signals impinging on uniform linear arrays by using estimation of signal parameters via rotational invariance technique (ESPRIT). This ESPRIT, based on GUI, presents easiness to enter parameters (variables) and show the results and it also presents low computational complexity in comparison to other DOA methods as well as it veducing the computation time. Computer simulations by using MATLAB 2009a program are used to evaluate the incident signals directions on an antenna array. Statistical analysis for element spacing, number of sensors and number of snapshots are included in this simulation.
