Bourennane}, country = {}, institution = {}, abstract = {In this paper, we propose a novel method for subspace estimation used high resolution method without eigendecomposition where the sample Cross-Spectral Matrix (CSM) is replaced by upper triangular matrix obtained from LU factorization. This novel method decreases the computational complexity. The method relies on a recently published result on Rank-Revealing LU (RRLU) factorization. Simulation results demonstrates that the new algorithm outperform the Householder rank-revealing QR (RRQR) factorization method and the MUSIC in the low Signal to Noise Ratio (SNR) scenarios. }, journal = {International Journal of Aerospace and Mechanical Engineering}, volume = {1}, number = {3}, year = {2007}, pages = {196 - 199}, ee = {https://publications.waset.org/pdf/5172}, url = {https://publications.waset.org/vol/3}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 3, 2007}, }
