A Novel Sparse recovery based DOA estimation algorithm by relaxing the RIP constraint
Abhishek Aich, P. Palanisamy
Direction of Arrival (DOA) estimation of mixed uncorrelated and coherent sources is a long existing challenge in array signal processing. Application of compressive sensing to arra…
A novel CS Beamformer root-MUSIC algorithm and its subspace deviation analysis
Abhishek Aich, P. Palanisamy
Subspace based techniques for direction of arrival (DOA) estimation need large amount of snapshots to detect source directions accurately. This poses a problem in the form of compu…
On-Grid DOA Estimation Method Using Orthogonal Matching Pursuit
Abhishek Aich, P. Palanisamy
Direction of Arrival (DOA) estimation of multiple narrow-band coherent or partially coherent sources is a major challenge in array signal processing. Though many subspace- based al…
