چکیده
1057 Abstract—This paper presents the use of Inverse Free Krylov Subspace Algorithm (IFKSA) with Estimation of Signal Parameter via Rotational Invariance Technique (ESPRIT), for Direction-of-Arrival (DOA) estimation using a Sparse Linear Array (SLA) of antenna elements. The use of SLA reduces the hardware requirements and the production cost. The SLA generates the sparse data, the pure signal subspace is first decomposed from the received corrupted signal space using IFKSA and later, ESPRIT is used to estimate the DOAs. Computer simulations are used to evaluate the performance of the proposed algorithm.

متن کاملDirection of Arrival Estimation Based on MUSIC Algorithm Using Uniform and Non-Uniform Linear Arrays
In signal processing, the direction of arrival (DOA) estimation denotes the direction from which a propagating wave arrives at a point, where a set of antennas is located. Using the array antenna has an advantage over the single antenna in achieving an improved performance by applying Multiple Signal Classification (MUSIC) algorithm. This paper focuses on estimating the DOA using uniform linear...
