Study of Signal Estimation Parameters via Rotational Invariance Technique by Using Ants Colony Optimization Algorithm

Abstract

In this paper, an algorithm based on Ants Colony Optimization (ACO) isproposed for extraction of the Directions of Arrival (DOA) of several signalsimpinging on uniform linear arrays. This algorithm is used to reduce thecomputation time and complexity that occur in Estimation of Signal Parametersvia Rotational Invariance Technique (ESPRIT). In order to illustrate the accuracyand flexibility of the proposed algorithm, several simulation cases introduce ofESPRIT-DOA estimation by using ACO algorithm in environment of Matlab 7.8program. Results are statistically analyzed in order to conclude from it thealgorithm's accuracy and reliability
