Post-Processing for Resolution Improvement of the MUSIC Algorithm

Lu Ming & Bao Zheng (Xidian University, Xi'an) .  
This paper presents a new algorithm for the high-resolution estimation of arrival angles of narrowband plane waves. In the algorithm, a post-processing technique is used to decrease the perturbation caused by noises. The post-processing of the noise subspace includes constructing a matrix composed of the elements of the vectors which are in the noise subs-pace and replacing the matrix by its reducing rank approximation. The simulation results have shown the effectiveness of the algorithm.
